Title: Multirate serial viterbi decoder for code division multiple access system applications
Inventor: KINDRED DANIEL RAY
IPC: H04B1/707
Filed: 1994-09-23
Abstract: A Viterbi decoder (20) for recovering the original bit data stream that was convolutionally encoded as a code symbol stream in a Code Division Multiple Access (CDMA) mobile communication system (22). The decoder (20) simultaneously decodes at the several data rates associated with certain multirate vocoders. The decoder (20) can decode at an unknown data rate in either continuous or framed packed modes. It accomplishes this by simultaneously decoding at multiple rates and by creating one or more data quality metrics for each decoded data packet. Special input and output buffering is provided to isolate the decoder (50) from system timing constraints.  The input buffer (48) includes selection and accumulation logic to organize code symbol data into the packet order for repeat mode or random burst mode at lower frame data rates. Decoded data packets for each of several predetermined data transfer rates are held in an output buffer (54) for about half of the decoding cycle, thereby permitting the system microprocessor to examine and select the appropriate decoded data packet. The decoder (50) also can be reconfigured to operate at any one of several predetermined convolutional encoding algorithms The Viterbi decoder (20), implemented as a single monolithic integrated circuit, can be used in any and all of many different multiuser telecommunications channels.

Filed: 1994-10-27
Abstract: A system and method for defining a process structure for performing a task is disclosed. The system comprises a computer, having a data storage memory, a keyboard for inputting data and a screen. A user inputs a first process definition which comprises a verb word and an object word defining the task for which a structure is to be created. The user is then able to define subsequent process definitions which are a predicted consequence of executing the first process definition or a predicted constituent step in executing the first process definition.  By analysing each process definition at each stage a complete process structure for performing the task can be built up and refined. The user is also able to specify particular object words falling within the meaning of the object word of a particular process definition which can be called up in tabular form on the screen, overwriting the display of process definitions in the process structure.

Inventor: UETSUKA HISATO
IPC: G02B6/124
Filed: 1996-08-29
Abstract: A width of a core in an optical waveguide is decreased in accordance with a predetermined value, as a distance of a position of the core to the centre position thereof is decreased. Consequently, a rectangular spectrum property having no ripple is obtained on a lower wavelength side in a reflection grating. In addition, the width of the core is changed at the position Z in the direction of light propagation, while UV light is radiated to the core, so that a periodically-striated distribution of refractive indices having an envelope which is changed in accordance with a value of "¦sin(C~Z)¦/¦C~Z¦" is formed in the core of the optical waveguide, and the phase of light to be propagated in the direction of light propagation is shifted at the position Z as defined below by .pi..        Z=m.pi./C(m=...,-3,-2,-1,1,2,3,...) Thus, a rectangular spectrum property is obtained in a low-reflection grating.

Title: Block and graft copolymers and methods relating thereto
Inventor: HOFFMAN ALLAN S
IPC: C08L71/02
Filed: 1995-03-03
Abstract: There is disclosed block and graft copolymers which, in one embodiment, contain both a temperature-sensitive polymer component and a pH-sensitive polymer component, and the use of such copolymers for topical drug delivery to a treatment area. The block and graft copolymers may be physically mixed with one or more drugs to form a copolymer-drug mixture. This mixture may be applied to the treatment as solid particles suspended in a pharmaceutically acceptable carrier, or as a liquid which gels upon contact with the treatment area. Upon contact with the treatment area, the pH-sensitive polymer component hydrates and swells, thereby causing release of the drug from the mixture. In addition, such hydration and swelling causes the pH-sensitive polymer component to adhere to the tissue of the treatment area, thus prolonging contact time. The temperature-sensitive polymer component resists hydration and swelling of the mixture, thereby imparting a sustained and controlled release of the drug to the treatment area. In another embodiment of this invention, bloc and graft copolymers, and hydrogels thereof, are disclosed having broad industrial applicability.

Patent CA-2189576-A1 (CA)
Inventor: IYODA MOTOMI
IPC: B60R21/01
Filed: 1996-11-04
Abstract: A CPU 30 first receives data of accelerations Gx and Gy applied respectively along a longitudinal axis and a lateral axis of a vehicle (S20).  The CPU 30 then calculates an arithmetic value fx from the acceleration Gx in the longitudinal direction according to specified arithmetic-operations, and calculates an arithmetic value fy from the acceleration Gy in the lateral direction according to specified arithmetic operations (S22). The CPU 30 subsequently projects vectors based on the arithmetic values fx and fy in a preset direction a to yield projective components of the vectors, and determines a sum fa of the projective components (S24).  The CPU 30 compares the projective component fa with a threshold value fth(a) previously set for the direction a, and determines whether or not the projective component fa is greater than the threshold value fth(a) (S26). On determining that the projective. component fa is greater than the threshold value fth(a), the CPU 30 generates an activation signal to activate air bag units 60 to 66 (S28). The structure of the present invention does not require the calculation of the magnitude or the direction of a composite vector, thereby eliminating complicated and time-consuming arithmetic operations.  No division is included in the required arithmetic operations, so that the result of calculation does not diverge.

IPC: H04W4/90
Filed: 1996-08-20
Abstract: A communication system (115) receives a paging signal (103) from a mobile station (100) requesting service and, if the paging signal (103) contains information identifying the service request as an emergency (502), a communication channel in a base transceiver station (105, 107, 109) is directly allocated to service the mobile station (100). If a communication channel is not immediately available, the communication system (115) will try to make a communication channel available. A distinct aspect of the communication system (115) is that it monitors an indicator (600) representative of the emergency call traffic on the communication system (115). Based upon the status of the indicator (600), the communication system (115) takes appropriate measures (440) to provide priority service for those mobile stations (100) having a priority access class. By providing priority service in this manner, the communication system (115) efficiently allocates the communication resource to the mobile stations (100) with priority access classes which need those resources urgently.
