Abstract:
The invention discloses a method, client and server for implementing the question and answer services. The method includes: by a first client, putting a question into presence information for publishing so that a second client obtains the presence information that contains the question; receiving an answer to the question sent by the second client through an instant message; and displaying the received answer together with the corresponding question. The invention fully utilizes the interpersonal network information in an instant messaging system, and implements the question and answer services based on the presence service and the instant messaging service in the instant messaging system. Therefore, users can ask questions and obtain answers conveniently based on the widely applied instant messaging system.
Abstract:
A wafer-level packaged IC is made by attaching a cap wafer to the front of an IC base wafer before cutting the IC base wafer, i.e. before singulating the plurality of dies on the IC base wafer. The cap wafer is mechanically attached and electrically connected to the IC base wafer, then the dies are singulated. Electrically conductive paths extend through the cap wafer, between wafer contact pads on the front surface of the cap and electrical contact points on the IC base wafer. Optionally, the cap wafer contains one or more dies. The IC base wafer can be fabricated according to a different technology than the cap wafer, thereby forming a hybrid wafer-level package. Optionally, additional “upper-level” cap wafers (with or without dies) can be stacked to form a “multi-story” IC. Optionally, a hermetically-sealed cavity headroom is provided.
Abstract:
Systems and methods for slow tail compensation are provided. A photodetector signal is pre-amplified to thereby produce an uncompensated photodetector signal that includes a fast component and a slow component. The fast component is removed from the uncompensated photodetector signal to thereby produce a compensating signal that includes the slow component of the uncompensated photodetector signal. The compensating signal is subtracted from the uncompensated photodetector signal to thereby produce a compensated photodetector signal that includes the fast component but not the slow component.
Abstract:
A thermal accelerometer device that allows up to three axes of acceleration sensing. The thermal accelerometer includes a substantially planar substrate, a cavity formed in the substrate, a heater element, and at least first and second temperature sensing elements. The heater element is suspended over the cavity, and the first and second temperature sensing elements are disposed along the X or Y axis in the substrate plane on opposite sides of and at equal distances from the heater element. The thermal accelerometer employs differential temperatures detected by the temperature sensing elements to provide indications of acceleration in the X or Y directions. Further, the thermal accelerometer employs a common mode temperature detected by the temperature sensing elements to provide an indication of acceleration along a Z axis perpendicular to the X and Y axes.

An Extensible Markup Language (XML) document management method includes: receiving an XML document management operation request sent via an XCAP protocol, by an XML Document Management Server (XDMS); determining that the XML document management operation request is in an entrustment mode, and determining whether to perform an operation described in the XML document management operation request in accordance with access permission information corresponding to an XML document, by the XDMS.
Abstract:
The present invention discloses a method for realizing presence service. By recording a correlation between a watcher identity and a class in an authentication configuration information of a presentity for a watcher and making presence information related to a corresponding class in the presence information issued by the presentity, a presence server determines that presence information may be obtained by the watcher according to a correlation between classes and watcher identities and presence information. The invention further discloses a system for realizing presence service, a presence information processing device and a presentity client.
Abstract:
A thermal accelerometer device that provides a compensation for sensitivity variations over temperature. The thermal accelerometer includes signal conditioning circuitry operative to receive analog signals representing a differential temperature is indicative of a sensed acceleration. The signal conditioning circuitry includes serially connected A-to-D and D-to-A converters, which implement a temperature dependent function and process the received signals to provide a compensation for sensitivity variations over a range of ambient temperature. To provide a ratiometric compensation for variations in power supply voltage, a buffered voltage proportional to the supply voltage is provided as a reference voltage to the D-to-A converter. The thermal accelerometer includes a self-test circuit for verifying the integrity of a heater, temperature sensors, and circuitry included within the device.
