Abstract: Systems and methods for providing secure application support for NFC devices in both battery on and battery off modes are provided. A first application that requires available host battery supply and a second application that does not require available host battery supply are loaded onto a mobile device. When the second application is enabled, the reader requests user input on a POS device. The first application is enabled when host battery supply is available, and the second application is enabled when no host battery supply is available.

Abstract: A frame buffer having a size of one video frame of a video stream is provided. The video stream has a source frame rate. Image data units of the video stream are written consecutively to the frame buffer in accordance with a circular buffering scheme and in real-time response to the video stream. Image data units are read from the frame buffer in accordance with the circular buffering scheme with a frame rate that is twice the source frame rate so as to generate a target video stream having a frame rate which is twice the source frame rate. The frame buffer can be used in a real-time video system, for example in a vehicle.

Abstract: A Low-Voltage Differential Signaling (differential signaling) driver circuit (10) comprising enable circuitry for enabling and disabling the differential signaling driver circuit (10) in accordance with an control signal is described. The differential signaling driver circuit (10) comprises: a differential output (12, 13) connected or connectable to a differential signaling receiver circuit via a differential transmission line; current control circuitry (14) for driving a signal current through the differential output (12, 13) in accordance with a driver signal; feedback circuitry (16) for driving the current control circuitry (14) to counteract a difference between a common mode voltage of the differential output (12, 13) and a reference voltage from a reference voltage provider; and the enable circuitry (18). The feedback circuitry (16) comprises a common mode node (20) for providing the common mode voltage (Vcm), a reference input (22) connected or connectable to the reference voltage provider, and a feedback input (24). The enable circuitry (18) is arranged to connect the feedback input (24) to the common mode node (20) when the differential signaling driver circuit (10) is in an enabled state and to the reference voltage provider when the differential signaling driver circuit (10) is in a disabled state. A method of enabling (5.1) and disabling (5.2) a Low-Voltage Differential Signaling (differential signaling) driver circuit (10) is also proposed.

Abstract: A test chamber is used within a system for testing microelectromechanical systems (MEMS) pressure sensors. The system includes a processor, two air tanks pressurized to different air pressures, a high speed switch mechanism, and the test chamber. The test chamber houses a MEMS pressure sensor to be tested, a control pressure sensor, and a temperature sensor. The MEMS pressure sensor and the control pressure sensor are located in a cavity within the test chamber. The cavity is of minimal size and has a domed inner surface. A response time of the MEMS pressure sensor within the cavity can be characterized by utilizing the system and subjecting the MEMS pressure sensor to a pressure stimulus pulse produced by switching between the two air tanks.

Abstract: An embodiment of a microwave heating apparatus includes a solid state microwave energy source, a chamber, a dielectric resonator antenna with an exciter dielectric resonator and a feed structure, and one or more additional dielectric resonators each positioned within a distance of the exciter resonator to form a dielectric resonator antenna array. The distance is selected so that each additional resonator is closely capacitively coupled with the exciter resonator. The feed structure receives an excitation signal from the microwave energy source. The exciter resonator is configured to produce a first electric field in response to the excitation signal, and the first electric field may directly impinge on the additional resonator(s). Impingement of the first electric field may cause each of the additional resonators to produce a second electric field. The electric fields are directed into the chamber to increase the thermal energy of a load within the chamber.

Abstract: A method for managing thread execution in a processing system is provided. The method includes setting a first watchpoint, and generating a first watchpoint trigger corresponding to the first watchpoint. In response to the first watchpoint trigger, execution of a first thread is controlled in accordance with a value stored in a first control register. Controlling the first thread may further include disabling execution of the first thread. The disabling execution of the first thread may occur within the first watchpoint region.

Abstract: A device includes multiple ceramic capacitors and a current path structure. A first ceramic capacitor includes a first ceramic material between first and second electrodes. A second ceramic capacitor includes a second ceramic material between third and fourth electrodes. The second ceramic material has a higher Q than the first ceramic material. The current path structure includes a lateral conductor located between the first and second ceramic materials, and first and second vertical conductors that extend from first and second ends of the lateral conductor to a device surface. The device may be coupled to a substrate of a packaged RF amplifier device, which also includes a transistor. For example, the device may form a portion of an output impedance matching circuit coupled between a current carrying terminal of the transistor and an output lead of the RF amplifier device.

Abstract: Methods and apparatuses are provided for evaluating or testing stiction in Microelectromechanical Systems (MEMS) devices utilizing a mechanized shock pulse generation approach. In one embodiment, the method includes the step or process of loading a MEMS device, such as a multi-axis MEMS accelerometer, into a socket provided on a Device-Under-Test (DUT) board. After loading the MEMS device into the socket, a series of controlled shock pulses is generated and transmitted through the MEMS device utilizing a mechanized test apparatus. The mechanized test apparatus may, for example, repeatedly move the DUT board over a predefined motion path to generate the controlled shock pulses. In certain cases, transverse vibrations may also be directed through the tested MEMS device in conjunction with the shock pulses. An output of the MEMS device is then monitored to determine whether stiction of the MEMS device occurs during each of the series of controlled shock pulses.

Abstract: A data processing system can comprise a first module having a workspace and configured to execute a task that can request access to a frame in a system memory, a queue manager configured to store a frame descriptor which identifies the frame in the system memory, and a memory access engine coupled to the first module and the queue manager. The memory access engine copies requested segments of the frame to the workspace and has a working frame unit to store a segment handle identifying a location and size of each requested segment copied to the workspace of the first module. The memory access engine tracks history of a requested segment by updating the working frame unit when the requested segment in the workspace is modified by the executing task.
