Abstract: In a digital-analog hybrid LSI including an analog circuit (2) and a digital circuit (3), the analog circuit (2) includes a circuit for sampling, according to the operation timing of a switch (4), information to be processed by the analog circuit (2) in a capacitor (5). A clock signal generating means (6) generates an operation reference clock signal (b) for the digital circuit (3) so that the change of the clock signal (b) is stopped at a timing when the switch (4) is opened, i.e., during a specified period (T) which includes the high-to-low transition timing of the clock signal. This prevents the analog characteristic of the analog circuit (3) from being degraded by digital noise that is transferred through the junction capacitance of the semiconductor chip (1).

Abstract: A method for the bi-directional transmission of digital data via an optical fibre is specified, by means of which in each case the bits of data streams to be transmitted are compressed packet by packet in constant number by factor of >2 to form bursts without changing the transmission rate. The bursts of one transmission direction are transmitted by a station in the intervals between the bursts of the other transmission direction from the respective transmitter via the optical fibre to the other station. To determine the transmission rates in the stations, mutually independent external clock generators are used at the two ends of the optical fibre. If the frequencies of the two clock generators deviate from one another, the bursts of the data stream with the lower transmission rate are in each case shifted by one bit width of the associated continuous data stream at intervals compared with the bursts of the other data stream. The respective receiver is informed of the shift in the bursts by the burst preceding the first burst to be shifted by means of at least one corresponding information bit.

Abstract: In a network for serving cordless stations located in microcells, speech channels are divided into channel groups such that no intermodulation products occur among the channels of each group. Base units are located respectively in the microcell sites to establish two-way speech channels with their cordless stations. Each base unit generates and updates priority values of the channel groups as representations of usages of all channels through a statistical process. Depending on the updated priority values different channel groups are uniquely assigned to the base units. Timeslots are defined uniquely by the respective base units using the identifiers of the assigned channel groups for broadcasting zone-registration polling signals during the defined timeslots to elicit a zone registration response from each cordless station.

Abstract: An optical time-division multiplexer (MUX) consists of multiplexing elements (ME) in which signal inputs (SE1, SE2) are connected with one another via optical waveguides (LWL) to a signal output (SA), carriers with different wavelength (Lambda 1, Lambda 2) being present in the signal streams (S1, S2) present at the signal inputs (SE1, SE2). The multiplexing elements (ME) are provided with a switchable filter (F) which is arranged preceding the signal output (SA) and alternately in each case absorbs one of the two signal streams (S1, S2) for the duration of the bit clock period (T). The multiplex signal (S1, 2) generated exhibits twice the bit repetition rate. Using switching elements in the form of through-connectable filters reduces the number of switching elements. Suitable switchable filters (F) are, in particular, multiple quantum well layer sequences which have a narrow-band absorption range. The advantage is that the different wavelengths can be closely adjacent to one another. The optical multiplexer is capable of multiplexing digital signals in such a manner that the pulse duration is shortened during the multiplexing. <IMAGE>

Abstract: A storage controller operates an array of parity protected data storage units as a RAID level 5. One of the storage units is a dedicated write assist unit. The assist unit is a temporary storage area for data to be written to the other units. When the array controller receives data from a host, it first writes the data to the assist unit. Because the assist unit is not parity protected and is only temporary storage, it is possible to write data to the assist unit sequentially, without first reading the data, greatly reducing response time. The array controller signals the CPU that the data has been written to storage as soon as it has been written to the assist unit. Parity in the array is updated asynchronously. In the event of system or storage unit failure, data can be recovered using the remaining storage units and/or the assist unit. The write assist unit also doubles as a spare unit. Data recovered from a failed unit can be stored on the write assist, which then ceases to function as a write assist unit and assumes the function of the failed storage unit.

Uniformity of image resolution and ease of signal processing enhancement is provided by transmitting adjacent ultrasonic beams at equal angular increments over the sector area. The ultrasonic beams transmitted are focused around predetermined transmit focal points and the transmit aperture employed for each transmission is determined by a transducer sensitivity criterion applied to the focal point. Means are provided for delaying signal components received from the beam directions so that the sum of the components will form a coherent echo signal. Means are provided for dynamically focusing received signal components by dynamically varying the sampling frequencies of laterally disposed signal components, and the receive aperture is dynamically varied in correspondence with the number of array elements which satisfy a sensitivity criterion at different depths of field.
