Title: Vehicle door latch with double locking
Inventor: FUJIHARA YOSHIHIKO
IPC: E05B77/28
Filed: 2008-07-30
Abstract: A vehicle door latch apparatus has a latch bolt 5 engaging a striker and released by outer or inner handles acting via outer 8 and inner 10 levers on an open lever. A lock lever 12 is pivotable to either prevent (fig. 5) or permit (fig. 3) the release operation of the outer lever 8. A sub-lock lever 13 is movable with the lever 12 between the locking and unlocking positions and is also movable by a motor 18 acting via a slide 20 to a double locking position (fig. 7) in which the release operation of the inner lever 10 is also prevented. A linkage 14, 15 moved by the outer lever 8 acts via an abutment 141 on the open lever 6. and inner lever 10 acts on the lever 6 via abutments 102 and 82 to move lever 8. Locking movement of the lever 12 causes a projection 123 to act on link 15 via slot 152 to move the abutment 141 out of alignment with lever 6. Initial operation of inner lever 10 causes interacting abutments 101, 131 to move lever 13 and hence lever 12 to an unlocking position and a subsequent operation of the lever 10 allows latch release. The slide 20 acts via a projection 210 in a slot 132 to move the lever 13 to a double-locking position in which abutments 101 and 131 are placed out of alignment to prevent any release action of lever 10. The lock lever 12 can be operated by either a linkage 11, 16 from a key lock or directly by a motor 17. Unlocking action by either key or motor on lever 12 will also release any double locking by consequent movement of lever 13.

Title: Evanescent field used to restore high frequncy in far field signal
Inventor: MAY JACK
IPC: H01Q15/00
Filed: 2008-09-26
Abstract: An antenna system 60, or a method of its operation, comprises processing a far field RF signal to restore high frequency components by producing an evanescent field which is focused on to a plane 72 where it is detected. The evanescent field is focused on to a detection plane 72 by a negative-refractive-index lens assembly 66 possibly including Pendry slab lenses. The evanescent field may be provided by a metal masking plate 64 with a plurality of apertures arranged in a grid which samples a far field RF signal. The diameter and effective path length of each aperture may be selected to obtain a desired gain profile. An aperture may be filled with dielectric material to adjust the effective path length of the aperture. The planar RF detector 72 may be an array of fractional wavelength antennas. Infinitesimal gaps are used between the elements of the system to avoid attenuation in the RF signal. The detected RF signal may then be subjected to digital signal processing to demodulate the far field RF signal received.

Title: Communication network inhibits or enables NAS signalling recovery after radio link failure
Inventor: CHIN CHEN-HO
IPC: H04W76/02
Filed: 2008-10-06
Abstract: A communication system comprises a Non Access Stratum (NAS) via which a network and user equipment (UE) communicate, and an Access Stratum (AS) providing physical connections to enable NAS communication between the network and UE. The physical connections include a radio link to the UE. Information is sent from the network to the UE to determine action of the UE in response to the failure of the radio link. Upon detecting a radio link failure (RLF), the UE performs a decided action according to the received information. The decided action may comprise NAS signaling recovery procedure, e.g. triggering a service request, tracking area update (TAU) or routing area update (RAU), dependent upon what information the UE has previously received from the network, i.e. the network may have sent information to inhibit/prevent or enable NAS signaling recovery after a RLF. Hence, network operators may remotely set or configure the UE, in terms of what action it takes after detection of a RLF, in order to 'switch on' or 'switch off' this NAS signaling recovery.

Title: Multi-stage combining weight calculation method and apparatus
Inventor: ROSENQVIST ANDERS
IPC: H04B7/08
Filed: 2009-02-25
Abstract: In a wireless receiver such as a Generalised RAKE (G-RAKE) or chip equalizer receiver, combining weights are calculated in multiple stages based on an overall system impairment covariance matrix and a grouping of signal processing delays. Computing the combining weights in multiple stages avoids having to invert the entire system impairment covariance matrix. Instead, smaller matrix inversions are performed. In one embodiment, a received signal is processed by calculating an impairment covariance matrix for a set of processing delays used to derive a plurality of signal values from the received signal. A set of intermediate combining weights is calculated for each of at least two different subsets of the processing delays based on the impairment covariance matrix. The signal values derived across the subsets of processing delays are combined using the sets of intermediate combining weights and the impairment covariance matrix.
