Abstract: RF tags may be used to acquire data. If the tag is attached to a particular article, information regarding that article may be acquired. In an example embodiment, items are fitted with RF tags. A mobile phone or other wireless device can track when the tags are in RF range. When a user wants to know data regarding the article, he may consult the information on the phone. The phones running the system may report any compatible tags that are found, even ones that have no ownership connection to a central server where the data is compiled. “Foreign” tag information is submitted to the server and can be turned over to the owner of the tags. In this implementation, the reach of the system may be increased compared to the previous, local implementation. In an example embodiment, information may be anonymized in the server to deal with privacy concerns.

Abstract: An illustrative method of the present application is for use in updating an application program in memory of a network device. An application program having a length L1 is initially stored in memory of the network device from a memory address A1 to a memory address A2?1. A download procedure is performed by the network device to receive an updated application program having a length L2>L1. This updated application program is stored in the memory from a memory address A3=A2+(L2?L1) for the length L1, and continuing in a circular buffer fashion from the memory address A2 for the length L2?L1. The application program is then copied over with the updated application program beginning at the memory address A1. With this technique, if a failure occurs while copying over the application program, no portion of the original updated application program will be written over.

Abstract: A low voltage, low power, wideband quadrature divide-by-three frequency divider using a wideband low voltage, low power differential Muller C element with multiple inputs operates on quadrature input and quadrature output signals. This frequency divider can be used in frequency synthesizers and as quadrature local oscillator generator.

Abstract: In one illustrative example, a wireless network device of a low data rate wireless personal area network (WPAN) or the like includes a controller, memory for storing one or more application programs, and a wireless transceiver coupled to the controller and operative for communications in the wireless network. The controller is adapted to receive, through the wireless transceiver, an instruction which causes the wireless device to operate as a client in performing an OAD procedure for receiving the program from another wireless device which is operated as a server in the wireless network, and to operate the wireless device as the client in performing the OAD procedure in response to such instruction.

Abstract: An amplifying circuit includes an n-type transistor having a source, a gate coupled to a first bias voltage, and a drain coupled to a first supply voltage through a first impedance circuit. A p-type transistor of the circuit has a source coupled to the source of the n-type transistor, a gate coupled to a second bias voltage, and a drain coupled to a second supply voltage through a second impedance circuit. A first differential input is coupled to the gate of the n-type transistor through a first capacitor and to the gate of the p-type transistor through a second capacitor. A second differential input is coupled to the sources of the n-type and the p-type transistors. A third capacitor has a first end coupled to the drain of the n-type transistor, and a fourth capacitor has a first end coupled to the drain of the p-type transistor and a second end coupled to a second end of the third capacitor. An output of the amplifier circuit is provided at the second ends of the third and the fourth capacitors.
