Abstract: Signaling touch screen enabled devices is disclosed. A capacitive stylus has a body suitable for being hand held as a writing instrument. The body has a tip for interfacing with a capacitive touch screen display panel of a computer system. The stylus has an insulator disposed near its tip, which insulates capacitance of the stylus body. A switch selectively couples the tip to the remaining parts of the stylus body. A controller controls the switch. A mode selector on the body is responsive to being pressed to signal the controller for selecting one of multiple modes. The controller is configured to enter the selected mode responsive to the mode selector and is configured to control the switch unit to switch according to different signal patterns depending on a mode entered by the controller.

Abstract: A computer system has a touch sensitive display screen within a housing and a touch sensor, which is coupled to a bus. A processor and a memory are coupled to the bus. The housing has a channel for receiving and storing a stylus. A sensor is disposed adjacent to the channel. The sensor interacts with the stylus through the Hall effect caused by a magnet within the stylus and is thus operable for detecting a presence or absence of the stylus without physical contact therewith. The memory has an application which, when executed on the processor, automatically performs one or more stylus related software functions upon a reported absence of the stylus from the channel. One of the software functions includes palm detection rejection with respect to data from the touch sensor. Another function includes display of a GUI displaying a listing of applications that are based on stylus data entry modes. Another function includes setting up OS modes designed for accurate operation of stylus data entry.

Abstract: Multiple transport channels (405, 406, 407) are multiplexed and transmitted in a single physical channel. A code (TFCI) is added to the transport channel data flows to indicate which processing schemes, from a set of available schemes, are being employed and the resultant blocks are interleaved. The depth of the interleaving is set in dependence on the transmission time intervals associated with the schemes in the set of processing schemes.

Abstract: In a flexible layer one (403) of a GERAN transmitter device, a TFCI, which indicates a particular combination of cyclic redundancy check, channel coding and rate matching, is generated by a TFCI generating process (412) using information from the medium access control layer. The TFCI is coded by a coding process (413), and inserted into the data stream by a TFCI insertion process (414). Each code has more bits than the corresponding TFCI, and identifies uniquely the TFCI. The coded TFCI is spread across the pre-interleaved block with portions placed in fixed positions in each burst. Interleaving is then performed by an interleaver (411). The coded TFCI used with a half-rate channel is the central segment of the coded TFCI used in the corresponding full-rate channel. The additional loss is so small as to be insignificant, but the FER performance is significantly improved, compared to using the full-rate codes, as a result of the increased payload of the content data bits.

Abstract: A device and a method for determining a reference level for automatic gain control of a radio frequency signal to be received, particularly having a varying strength, in which method frames of a logical general packet control channel are received, as well as frames which have been transmitted with a predetermined transmission power level and by using a predetermined way of controlling the transmission power level. In the invention, said reference level is determined on the basis of at least one frame of a received radio block, or on the basis of at least one preceding frame, or on the basis of both of these, wherein the reference level is corrected on the basis of the signal strength measured during their reception.

Abstract: This disclosure provides a stand alone printing optical disc player/recorder for use in connection with CD's, DVD's, and Mini-Discs. In a particular embodiment the printing player/recorder has a combined player/recorder unit and an inkjet printer. Using a platter transport the printer player/recorder is capable of reading or writing information to a provided optical disc and then printing a label upon the optical disc without removing the disc from the system. The label printed may also be generated from the information read from or written to the optical disc itself thereby insuring a match between the label and the information encoded upon the optical disc. Associated methods of use are also provided.
