摘要:
An integrated circuit (IC) chip (100) expanded to nerve fiber (602) growth in the third dimension by through-silicon via-holes (TSV) (131), with an electrically conductive inner sidewall (303) having a roughness (303a) suitable for supporting the growing fiber and conductive connections (210) to the circuitry (101). The TSVs are fabricated parallel to each other and may be arrayed in regular patterns. The chip, provided with a pad (230) for contacting a nerve end and attaching a neuron, acts as a permanent protective sheath for the parallel growing fibers. Nerve fiber growth is stimulated by combining in the chip electrical and magnetic pulses and neurotrophic factors (603); continuous communication with external monitors is provided. The IC provides each TSV with a signal generator, electric and magnetic field generator, power source, potential sensor, and transceiver. The electronic signals may initiate a predetermined action potential in the adjacent nerve fiber end and a sensor is configured for sensing the action potential in the nerve fiber end.

In one form of the invention, a process of sending real-time information from a sender computer (103) to a receiver computer (105) coupled to the sender computer (103) by a packet network (100) wherein packets (111,113) sometimes become lost, includes steps of directing (441) packets (111) containing the real-time information from the sender computer (103) by at least one path (119) in the packet network (100) to the receiver computer (105), and directing packets (113) containing information dependent on the real-time information from the sender computer (103) by at least one path diversity path (117) in the packet network (100) to the same receiver computer (105). Other forms of the invention encompass other processes, improved packets and packet ensembles (111,113), integrated circuits (610), chipsets (DSP 1721, MCU), computer cards (1651), information storage articles (1511,1611), systems, computers (103,105), gateways (191,193), routers (131,133), cellular telephone handsets (181,189), wireless base stations (183,187), appliances (1721,1731,1741), and packet networks (100), and other forms as disclosed and claimed.
摘要:
An apparatus and method for transmitting and receiving a bit stream. On the transmission side, coded bits (Y.sub.t) and an interleaved version of the coded bits (X.sub.t) are separately modulated and transmitted. On the reception side, a priori output probabilities produced by a probability generator (34) are combined (112) and then input to a SISO decoder (111). Combined a posteriori output probabilities (115) produced by the SISO decoder are split (113) and then fed back to the probability generator.

A wireless communication network (10) includes a wireless transmitter having a plurality of antennas (AT11, AT12). The transmitter includes for each of a plurality of different user channels (Dn), circuitry (22n) for providing a plurality of groups of symbols in a first symbol group sequence (D1n). Each of the plurality of different user channels includes circuitry (241n) for forming a first modulated symbol group sequence for the user channel by modulating the symbols in the first symbol group sequence with a unique code that corresponds to the user channel and distinguishes the user channel from each other of the plurality of different user channels and circuitry (261) for combining the first modulated symbol group sequences for transmission by a first antenna (AT11). Each of the plurality of different user channels includes circuitry (22n) for forming a second symbol group sequence (D2n) by time reversing symbols in at least some of the groups of symbols.

摘要:
Operands (90) that are represented in two's complement format are prepared for use in binary arithmetic. For each operand, it is determined (91, 93) whether an original value thereof is within a predetermined proximity of a maximum positive/maximum negative value boundary associated with the two's complement format. If any of the original operand values is within the predetermined proximity, all of the original operand values are adjusted (95) to produce respectively corresponding adjusted operand values (96) for use in a binary arithmetic operation.
摘要:
A method (70) of operating a wireless receiver (UST). The method receives a wireless communicated signal, wherein the signal comprises a first synchronization channel component. The method also correlates a synchronization channel value (PSC) to the signal to produce a plurality of correlation samples in response to a correlation between the synchronization channel value and the signal. Further, the method compares (72) the plurality of correlation samples to a threshold (τ) and stores as a first set of correlation samples selected ones of the plurality of correlation samples that exceed the threshold and are within a first time sample period, wherein each of the correlation samples in the first set has a corresponding sample time relative to the first time sample period. Finally, the method combines (74) a second set of correlation samples with the first set of correlation samples.
摘要:
The frequency hopping pattern of a first wireless communication device is modified such that each transmission (73) to a second wireless communication device is on a frequency (MSj+1) that the second device's normal frequency hopping pattern specifies for one of the second device's next several transmissions to the first device. This permits the second device to make quality measurements (54) on a frequency that the second device will soon use (51) for transmission to the first device.
