Title: Transplantation of Sertoli cells
Inventor: SANBERG PAUL R
IPC: A61K35/30
Filed: 1996-03-13
Abstract: The transplantation of Sertoli cells, particularly with a view to the treatment of neurological disorders such as Huntingdon's, Parkinson's and Alzheimer's diseases, is described. In a rat model, methods for the preparation of Sertoli-cell enriched fractions and the transplantation of these cells into the brain in the striatum ipsilateral to the substantia nigra are disclosed. In addition, the Sertoli cells are also co-transplanted with neural cells or adrenal chromaffin cells. Sertoli cells were tagged with latex beads or fluorescent dyes which enabled their histological localisation. It is considered that growth factors and immunosuppressive factors derived from Sertoli cells facilitate allograft acceptance.

Title: Electromagnetically actuated valve with thermal compensation
Inventor: ZIMMERMANN DANIEL E
IPC: F01L9/20
Filed: 1997-11-04
Abstract: An electromagnetically actuated valve comprises a valve with an electromagnet, an armature and at least one resilient member. The armature is biased by a resilient member such that when the electromagnet is off the armature is biased to a position spaced from an end of the electromagnet and when the electromagnet is on a resilient member is compressed until the armature is abutted against the electromagnet. A compliant member 50 is coupled between the shaft of the valve 22 and the armature 16 such that the armature 16 may move relative to the shaft of the valve 22 to compensate for mechanical tolerances including thermal expansion or contraction. The movement of the armature 16 on the shaft allows the valve to be properly seated and the armature 16 to have a zero gap relative to the electromagnet, on activation. The compliant member 50 may be a spring washer and an adjustment member may be used to adjust the position of the armature 16 when the electromagnet is not activated.

Title: On-line missing/gained filament detection in multifilament winding
Inventor: THOMPSON DEWEY EDWIN
IPC: B65H63/00
Filed: 1997-12-04
Abstract: An on-line system and method monitor the build up of yarn package diameter and detect winding defects, including missing or gained filaments, in multifilamentary yarn spinning processes. The system and method derive and compare yarn package denier for several yarn packages wound on a common winding apparatus. Diameter ranges are used to divide a yarn package into various measurement zones (16). Denier measurements are derived for each zone from two on-line, real-time inputs: yarn package speed and time to traverse the specified zone. The apparatus operator is notified of out of tolerance measurements so that remedial action may be taken. The system also provides for constant and periodic updating of the denier measurement algorithm to account for process variations.

Title: Digital circuits with selectable low power and high speed alternative circuits
Inventor: SHELLEY ANDREW
IPC: H03K19/00
Filed: 1998-05-19
Abstract: In order to optimise power consumption of a digital circuit, two alternative circuits are provided. A first circuit has a low power consumption, but has a limited upper frequency of operation. A higher power circuit which can operate at higher frequencies is enabled when the frequency of operation exceeds the upper limit of the low power circuit. The low power circuit is then disabled. The technique may be applied in an adder, wherein carry look ahead logic is enabled by control line FULLSPEED when the frequency of operation is too high for a ripple carry arrangement. The method may be applied to subtracters and multipliers. The technique may also be applied in a state machine (figure 5), wherein one of next state decode circuits respectively optimised for low power or high speed may be selected. Low power or high speed circuits may be selected in dependence on the intended application or may be selected adaptively in dependence on the actual clock frequency.

Inventor: MANO YOSHIZUMI
IPC: H04N5/765
Filed: 1998-09-25
Abstract: A video recording device instantaneously captures stores video images displayed on a television 10. The images are preferably stored in a storage device comprising a hard disk drive 94 coupled to the television through an IEEE 1394 serial bus network. The instantaneous record operation is initiated by pressing an instantaneous record button on a remote control 16. In response, the information currently being displayed is simultaneously routed to the storage device. After storing the images, the viewer can replay the video by pressing an instantaneous playback button on the remote control. The recording device further includes the ability to record a program while concurrently playing back a previously recorded video broadcast. This previously recorded video broadcast can be the earlier recorded portion of the same program that is still recording or a different video broadcast. The viewer enters the data and commands for recording and playback preferably using the remote control. Once again, the video programs are preferably recorded and played back from the storage device. The recording device of the present invention can also be used to edit pre-recorded video. A pre-recorded video is preferably played using a conventional VCR 21 and television 10. Selected portions of the video can be recorded and stored in the storage device for later retrieval and further editing by the viewer. Preferably, the viewer initiates the edit/record operation when viewing a home video by pressing an editing record button on the remote control. The viewer can also add additional video, audio or other features.

Patent GB-2338075-A (GB)
Title: Colour plane under exposure for reducing edge effect in electrophotographic processes
Inventor: WIBBELS MARK
IPC: G03G15/01
Filed: 1999-03-18
Abstract: A method for reducing edge effect (white gapping) (155) between objects formed on a photoconductive member of an imaging device includes, during processing of a given colour plane, under exposing (partially exposing) (230) the photoconductive member (75) for image data that specifies a colour to be developed on at least one color plane but specifies no colour to be developed on the given colour plane. Under exposing occurs relative to a development threshold for the image processing of the given colour plane. As such, the under exposing does not enable development of that image data during image processing of the given colour plane. Preferably the under exposing occurs relative to a high frequency halftone screen for minimizing contamination (unwanted development) during the partial exposure. A half tone screen switching process (82) enables appropriate halftone exposure for objects embodying the given colour plane, and enables the necessary under exposure (utilizing the high frequency halftone screen) for objects not embodying the giver colour plane. By partially exposing objects (230) that do not include a colour to be developed on the colour plane currently being processed, and while normally exposing adjacent objects (235) that include a colour to be developed on the current colour plane, the lateral electric field effects (250) between the objects is reduced and, thus, toner development for the given colour plane is more edge precise for reduced white gapping between the objects. Also provided is an image forming device including a control apparatus for controlling the exposing apparatus.

Title: Avoiding underflow or overflow in a circular buffer
Inventor: WOOD ROBERT GEOFFREY
IPC: H04L25/05
Filed: 1999-05-28
Abstract: A method is provided for avoiding data loss in a data packet switch which utilizes a circular data buffer. If the data is received at a faster rate than it is read out of the buffer the data read-out pointer is adjusted by incrementing it to skip, or drop, the next sample. If the data is received at a slower rate than it is read out of the buffer, then the read-out pointer is adjusted by decrementing it to repeat the previous sample.
