DETAILED DESCRIPTION

The invention is further described as follows in combination with drawings and specific embodiments:

An embodiment as shown in FIGS. 1 and 2 relates to a centralized theft-proof or theft-prevention device, which comprises a main control 1, 3 sub-controls 2, and optionally a remote control 3. The remote control 3 is optional because it is convenient to have, but not necessary for the function of the system. The main control comprises a processor 11, a display 12, a wireless receiver 13, and an alarm 14. Each sub-control comprises a SCM 21 and multiple (e.g., 4 pairs shown) interfaces 22 electrically connected to the SCM 21. The processor 11 is in series connection with all SCMs 21 and is electrically connected to the display 12, wireless receiver 13, and alarm 14, respectively. Adapters 4 are used to connect the main control 1 and each sub-control 2. AS shown in the example of FIG. 1, an adapter 4 connects between the main control 1 and the first sub-control 2, and then further adapters 4 connect between the sub-control 2 in series. Note that while this example shows that the main control 1 connects with one series of sub-controls 2. However, in some embodiments, the main control 1 may have multiple adapters 4 to connect multiple series of sub-controls 2.

In accordance with some embodiments of the invention, one of the interfaces 22 in sub-controls 2 may be used to connect a charging stand via a charging line, while another one is connected to the digital product (i.e., display product) via a data wire.

As shown in FIG. 3, each sub-control 2 may comprise a charging line detection circuit (e.g., charging line detection circuit 5 shown in FIG. 3). In this example, the charging line detection circuit comprises resistor R6, resistor R7 and a capacitor C5. The terminals of resistor R7 are electrically connected to one terminal of resistor R6 and one terminal of capacitor C5, respectively. The other terminal of capacitor C5 is grounded, and the other terminal of resistor R6 is connected to a power source (a power source of 3.3V is shown in this example). The junction of resistor R6 and R7 is connected to SCM 21 of sub-control 2. The junction of resistor R7 and capacitor C5 is connected to poles G (gate) of MOSFET P and MOSFET N as is shown in FIG. 4.

As shown in FIG. 4, each sub-control may further comprise a charging status indication circuit 6, which comprises an LED1, an LED2, a resistor R1, a resistor R5, a MOSFET N and a MOSFET P. Poles S (source) of both MOSFET N and MOSFET P are grounded. The terminals of LED1 are respectively connected to one terminal of resistor R1 and pole D (drain) of MOSFET N. The terminals of LED2 are respectively connected to one terminal of resistor R5 and pole D of MOSFET P. Resistors R1 and R5 are connected to a power source (e.g., a 5V power source). Pole G of MOSFET P is connected to pole G of MOSFET N and then to a charging line that connects with the shell of a digital product.

When no digital product is connected, the pin connected to SCM as shown in FIG. 3 detects a high electrical/voltage level, indicating that no digital product is connected. When pole G of MOSFET N is at a high voltage level, MOSFET N is on and LED 1 is lit. When pole G of MOSFET P is at a high voltage level, MOSFET P is off and LED5 is off. When any digital product is connected, the pin connected to SCM as shown in FIG. 3 will detect a low voltage level, indicating that the digital product is connected, and the system enters the theft-prevention state. When pole G of MOSFET N is at a low electrical level, MOSFET N is off and LED1 is off. When pole G of MOSFET P is at a low electrical level, MOSFET P is on and LED 5 is lit.

In accordance with embodiments of the invention, each sub-control may comprise a charging control circuit. As is shown in FIG. 5, each sub-control 2 comprises a charging control circuit 7, which comprises a resistor R22, IRF7103 chips U6, U7 and an adapter interface J13; one terminal of resistor R22 is grounded; the adapter interface J13 comprises pins 1, 2 and 3. Pins 2 and 3 are short connected for connection with pin 5-8 of IRF7103 chips U6 and U7, respectively. Pin 1 of adapter interface J13 is connected to a power source (e.g., a 5V power source).

Pins 1 and 3 of IRF7103 chips U6 and U7 are grounded. The other terminal of resistor R22 and pins 2 and 4 of IRF7103 chips U6 and U7 are connected to the data wire.

When no data wire is connected, control poles G of IRF7103 chip U6 and U7 are at a low electrical level because the resistor R22 is grounded, and chips U6 and U7 are off. No current loop is formed because one terminal (positive pole) of the adapter is connected to a 5V power source, while the other terminal is connected to chips U6 and U7, which are off. As a result, the display product is not being charged. When the data wire is connected, a high electrical level is produced at one end of resistor R22, and control poles G of IRF7103 chip U6 and U7 are also at the high electrical level. Therefore, chips U6 and U7 are on, and the negative pole of the adapter is connected to form a power loop, which is used to charge the display product.

As is shown in FIG. 6, in accordance with some embodiments, a sub-control 2 connects with a charging stand 9 via a charging cable 966. The charging stand 9 has a groove 91, where an electrode assembly 911 may electrically connect with a mini plug 922, which in turn connects with a display product 15. Alternatively, the mini plug 922 connects with the display product 15 and also connects, via a cable 955 (optionally with a plug 944 at the other end of cable 955) to the charging stand 9. The charging line (charging cable) 966 (from the sub-control 2) is connected to the electrode assembly 911. The charging line 966 may connect with the sub-control 2 via an interface 10 (e.g., an USB interface).

As is shown in FIG. 6, in accordance with some embodiments, the system may use a charging stand (display stand) 18 that is connected to a sub-control 2 via a charging cable 17, which has an interface 16 at one end for connection with a display product 15 (e.g., a cell phone) and another interface 10 at the other end for connection with a sub-control 2. In this embodiment, the interface 16 may fit in a charging stand (display stand) 18 such that the display product 15 (e.g., a cell phone) is displayed while being charged. The interfaces 16 and 10 may be any suitable connection interface, such as an USB interface. The charging stand 18 also functions as a display stand for a display item (e.g., a mobile phone) 15.

In accordance with some embodiments of the invention, the charging stands on both sides of the groove may be provided with cavities filled with roller balls. Both walls of the groove may be made of an elastic material.

In accordance with some embodiments of the invention, the wireless receiver may be a 2.4 G wireless receiver or an RFID wireless receiver.

The operation of an embodiment of the invention may be as follows:

As is shown in FIGS. 1 and 2, the main control 1 makes use of data wire 4 to connect one sub-control 2; the sub-control 2 is connected to other sub-controls 2 via data wires in series, e.g., connecting 8 sub-controls 2 in this particular example.

SCM 21 of each sub-control 2 detects a voltage signal at each interface. For example, when a display product is connected to the third and fourth interfaces of the eighth (8th) sub-control, the SCM of the 8th sub-control will send information that “a display product is connected at the third and fourth interfaces” to the seventh (7th) sub-control. The 7th sub-control will then relay the information to the 6th sub-control. The information is similarly relayed up the chain. The information that “a digital product is connected” will finally reach the main control 1 for recording and/or display.

When the 3rd interface is connected to the product support (e.g., the charging stand 9 in FIG. 6) via a charging line (or charging cable), the charging plug on the product support may be used to charge the display product and the status indicator lamp is lit (e.g., a blue light).

When the charging line/cable is disconnected from the digital product, SCM of the 8th sub-control will send the information that “the 3rd interface is disconnected from the display product” to the 7th sub-control, and the 7th sub-control will then relay the information to the 6th sub-control. The information is relayed in turn in a similar manner. Finally, the information that “the 3rd interface is disconnected from the display product” will reach the main control to record and display the information, and to trigger an alarm. Meanwhile, status indicator lamp on the charging line will display in red.

In accordance with some embodiments of the invention, a remote control may be used to send unlocking information to the processor. The wireless receiver will receive the unlocking information; thereby the processor will control the alarm to stop the alarm.

It is to be understood that the above embodiments are only used to illustrate the invention, and should not be used to restrict its scope. It is to be further understood that one skilled in the art can make various alterations or modifications to the invention after reading of the contents described herein. Similarly, such equivalent forms also fall within the scope of the invention, as defined by the attached claims.
