Title: System and method for achieving efficient coordination of protection switching
Inventor: MANCHESTER JAMES S
IPC: H04M3/22
Filed: 1998-03-31
Abstract: SYSTEM AND METHOD FOR ACHIEVING EFFICIENT    COORDINATION OF PROTECTION SWITCHING       The delineation and quick invocation of protection switching is achieved by generating a protection indicator having an initial state at the point that a transmission facility failure is detected and passing the indicator downstream. A switch that receives the indicator either increments or decrements the indicator in accordance with predetermined rules. However, a switch that receives the indicator when it reaches an active state immediately invokes protection switching if that switch is at the sink end of an associated protection path.

Title: Fluid handler and method of handling a fluid
Inventor: MERRIAM RICHARD
IPC: G01F11/00
Filed: 1996-12-04
Abstract: Methods of fluid handling are disclosed. According to one method, a tip of a nozzle is moved below a surface of the fluid to be handled. A pump fluidly associated with the nozzle is energized to move fluid into the nozzle. A  pressure transducer fluidly associated with the nozzle is energized to monitor pressure within the nozzle. Pressure within the nozzle is substantially continuously monitored with the pressure transducer during operation of the pump. Based on the substantially continuously monitored pressure within the nozzle, it is determined whether movement of fluid into the nozzle is intended or unintended. Similar methods may be used to move fluid out to the nozzle.

Title: Method for producing yeast extract
Inventor: KUBOTA MASAKI
IPC: A23L1/28
Filed: 1998-04-16
Abstract: A process for producing yeast extract by which the coloration and odor characteristic to the extract can be relieved while leaving available components thereof such as amino acids intact. This method makes it possible to decolor and deodorize yeast extracts obtained by the conventional methods while scarcely reducing the contents of available components thereof such as amino acids. The obtained yeast extract can be blended with other materials and therefore usable in various fields including seasonings, cosmetics and health foods. Thus it is expected that the range of application of yeast extracts can be enlarged thereby.

Title: Line object scene generation apparatus
Inventor: CIHOLAS MIKE
IPC: H04N21/242
Filed: 1995-06-28
Abstract: The invention provides a system for recording and displaying a time sequential scene on a computer. The digital camera transmits a sequence of digital image frames to the timer representative of the image of a body passing a plane in space. Each frame represents a line object of the body, thus forming a fractional part of the scene. Once the frame reaches the image timer, it is digitally marked with a time reference and buffered into a block of information. The main control computer stores blocks of information from the image timer for a variety of processing and features available to the user. The invention also provides a selected memory, preferably a virtual memory subsystem, or hard-disc drive. Preferred constructions for adjusting camera pixel processing of light values, time-marking the images, creating colour palettes for interactive viewing of colour images, and video data coding to accommodate the high volume of line image data are described.
