Abstract: A sub-arm which is rotated together with an adjustment lever is fixed to a base end portion of the adjustment lever. A receiving side member is fixed to an outer surface of one support plate part of a support bracket and a buffer member made of an elastic material is fixed to the receiving side member. When the adjustment lever is rotated in a predetermined direction, a tip portion of the sub-arm first contacts the buffer member before step portions of driving and driven cam surfaces contact each other. Therefore, when the adjustment lever is rotated in the predetermined direction (a direction in which an axial dimension of a cam mechanism is contracted) so as to adjust a position of a steering wheel, it is possible to prevent generation of a harsh abnormal noise caused as the step portions of the driving and driven cam surfaces contact each other.

Abstract: When an adjustment lever 32 is rotated in order to adjust the position of a steering wheel 1, the adjustment lever 32 is prevented from vigorously rotating, which prevents making the driver who operates the adjustment lever 32 feel discomfort. An expandable damper 35 that provides resistance to the rotation of the adjustment lever 32 is provided between a protrusion 34 that rotates together with the adjustment lever 32 centered around an adjustment rod and an extending portion 37 that is provided on a support-plate portion 15c. The expandable damper 35 has a cylinder portion 38 and a damper rod 39 that are combined so as to be able to displace relative to each other in the axial direction by way of grease 40.

For example, the disclosure presents a method for identifying a plurality of frequencies for camping by the UE, wherein each frequency of the plurality of frequencies is associated with a radio access technology (RAT), sorting the identified frequencies into one or more frequency groups based on a priority associated with each of the identified frequencies, searching a frequency group with a first highest priority to detect a cell for camping by the UE, and camping on a cell detected by the UE. As such, a method and an apparatus for an improved acquisition mechanism at a user equipment (UE) is disclosed.

Abstract: A novel and improved method and apparatus, in a WCDMA communication system, for informing a mobile station of a downlink data frame time offset by determining the downlink data frame time offset, and transmitting the downlink data frame time offset via an Active Set Update message transmitted from a cell to mobile station. Once an Active Set Update message is received, the data frame time offset information is provided to a timing block which may determine data frame boundary of each downlink signal. Timing block may then adjust the PN sequence timing corresponding to the downlink signal associated with the data frame time offset such that corresponding data symbols in each data frame are correctly soft combined in a combiner.

Abstract: Techniques for efficient searching in asynchronous systems, such as W-CDMA, as well as multi-mode searching, are disclosed. In one aspect, step one and step three search are performed in a single search engine. In another aspect, a search engine is configurable to search the offsets of a slot in step one search, producing sequential hypothesis energies, and peak detecting and sorting those energies. In yet another aspect, the peak detector and sorter are configurable to perform step one searching or step three/multimode searching. Various other aspects of the invention are also presented. These aspects have the benefit of circuit area and search-time efficiency which translate into reduced costs, increased standby time, increased acquisition speed, higher quality signal transmission, increased data throughput, decreased power, and improved overall system capacity.

Abstract: The invention is a method for limiting the peak transmit power in a CDMA communication system. At least one of first and second high transmit power regions are separated into a plurality of high transmit power subregions. The high transmit power subregions of the plurality of high subregions are shifted by time offsets of differing durations to provide a plurality of time offset subregions. First and second low transmit power regions are also provided. At least one of the first and second low transmit power regions is also separated into a plurality of transmit power subregions and the low transmit power subregions are shifted by time offsets of differing time durations. The subregions can be time offset by a predetermined time duration or by a random time duration.

Abstract: A method and apparatus for using information about a mobile terminal's location relative to a base station can improve performance of a communication system. In addition, information about the mobile terminal's velocity relative to the base station may be used to improve performance of the communication system. The location information may be used to estimate a nominal PN offset, and a set of PN offset to use, for processing communication signals.

Abstract: An improved method for facilitating handoff between an asynchronous and a synchronous base station. A method for determining a pilot channel PN offset of a pilot channel transmitted by a wireless base station. In a first embodiment, the method includes correlating a PN sequence with a received pilot signal to acquire a PN frame timing, receiving at least one search code burst aligned with the PN frame timing, the at least one search code burst signifying the pilot channel PN offset, and comparing the at least one search code burst to a set of codewords, each codeword representing a predetermined PN offset. From the search code bursts, the mobile station is able to quickly determine the PN offset of the transmitting base station, and thereby identify it. Methods for transmitting a complementary set of forward link channels are also disclosed.
