A pager system in which individual pagers have a database is disclosed. The database can be updated by transmitting a mask code and update data. The mask code indicates a mask stored in the individual pager itself which receives the data. Using the mask code, the mask is identified and used to indicate positions in the database where data is to be written.

Briefly, in accordance with one embodiment of the invention, an adaptive equalizer comprises: a digital filter including filter tap coefficients; a slicer; and a filter tap coefficient update block. The filter, slicer and coefficient update block are configured so as to perform at least one burst update of the filter tap coefficients. In accordance with another embodiment of the invention, a method of updating the filter tap coefficients of an adaptive equalizer comprises the step of: performing...

A time-division switching system including first and second control units operating in accordance with a generic program is disclosed. After a new generic program is stored in the second control unit, the first control unit still operating in response to the old generic program initiates the performance of a test sequence by the second control unit. The first control unit times the execution of the test sequence. When the test sequence is not completed within a predetermined period of time or wh...

A position encoder for providing signals that reflect the position of an object is contained in a housing which can be rotated back and forth to update the encoder. The encoder comprises a sun gear and a planet gear, and these gears are connected to an object. From the rotation of these gears, those signals that reflect the position of the object are generated. Rotating the case causes the gears to rotate relative to each other and to sensors which produce the signals. By rotating the case back ...

An update client sends to an update server which is connected to the update client via a communication line, identification information of a driver and firmware which are included in a disk array system, and identification information of an error event which has occurred in the disk array system. The update server determines whether update of the driver and the firmware is necessary or not in accordance with a combination of the supplied identification information of the driver, the firmware, an...

An update unit for an array in an integrated circuit is provided. The update unit delays the update of the array until a clock cycle in which the functional input to the array is idle. The input port normally used by the functional input is then used to perform the update. During clock cycles between receiving the update and storing the update into the array, the update unit compares the current functional input address to the update address. If the current functional input address matches the u...

An update management system provides access to software updates (patches and upgrades) and to an update catalog server. The catalog server includes a chronology generator. When a request for an update family tree for a target update is received, the chronology generator accesses an index to find the database and record number for the target update. The record is retrieved, indicating updates superseded by the target update and updates superseding the target update. Records for the superseded and...

A processor which includes a fetch program counter circuit and an execute program counter circuit is disclosed. The fetch program counter circuit provides less significant program counter value bits in addition to a fetch program counter value. The execute program counter circuit generates an execute program counter value using the less significant program counter value bits. The execute program counter circuit receives a plurality of less significant program counter bit values and selects a sin...

A method and apparatus for checking/updating existing software on a user's computer utilizes a graphical user interface (GUI). The GUI enables the user, without knowing what software exists on the computer, to download a text file from a remote server and check whether the software on the remote server is contained on the user's computer. The user can also download and automatically install a new or updated program via the GUI.

A wireless interface device is adapted to be interfaced with a host computer by way of a radio link. A wireless interface device includes one or more flash memory devices that are adapted to be updated by the host computer over the radio link.
