Title: Hand held data collection computer terminal having power management architecture including switchable multi-purpose input display screen
Inventor: DANIELSON ARVIN D
IPC: G06F3/02
Filed: 1995-09-18
Abstract: A portable data collection terminal has an elongate housing with a hand grip conforming rear surface.  A front surface features a numerical keyboard adjacent a lower end of the housing and an LCD screen adjacent the keyboard toward an upper end of the housing.  The display screen is of elongate rectangular shape, its length extending longitudinally of the housing of the data terminal. The active area of the display screen is covered by a touch sensitive overlay screen which is configured in one mode of operation of the data terminal into an alphabetical keyboard.  The orientation of the display is switchable between orientations in which the line direction of the displayed data extends across or longitudinally of the data terminal.  The keys of the numerical keyboard are identified by indicia disposed on a template.  The orientation of the template may be sensed to switch the orientation of the displayed data and touch sensitive key identifiers to correspond to the orientation of the indicia on the template.  As a further embodiment an electromagnetic activation by a pen may be used to enter data into a data terminal.  Power saving shutdown extends the battery life of the data terminal.  A shutdown mode permits resumption of operations by depression of a key.  During operations power consumption is reduced by efficient distribution of operations control between microprocessors.  The microprocessors have shared access to and control of system operations.

IPC: B42D15/00
Filed: 1995-12-01
Abstract: A personalized life insurance policy is one which provides a unique schedule of death benefits and a unique schedule of cash surrender nonforfeiture benefits for the life insured by the policy. The schedules are selected and agreed upon by the company providing the insurance (hereinafter referred to as the Insurer) and by the policyholder and are unique to that policy. The schedule of death benefits defines for each point in time in the future the death benefit expected to be paid should the life insured die at that point in time. The schedule of cash surrender nonforfeiture benefits defines for each point in time in the future the cash amount available should the life insured terminate the insurance coverage at that time. To date, schedules of death benefits and cash surrender nonforfeiture benefits in life insurance policies have been determined by class of life insured and/or by formula defined by Insurers. Customized schedules for which the policyholder participates in the determination have not been offered.

Patent CA-2177512-A1 (CA)
Inventor: SHULTZ JEFFREY R
IPC: D06N3/00
Filed: 1996-05-28
Abstract: The present invention discloses surface covering products and methods and an apparatus for making surface covering products. In particular, the method of the present invention includes depositing color particles on a moving carrier to form a base layer.   The base layer then comes in contact with a patterned embossing device such as a roll to create a depressed or displaced pattern image on the base layer.  Afterwards, accent particles or pellets are sprinkled or applied over the embossed base layer. The embossed base layer is subjected to heat and/or pressure to consolidate the accent and color particles and form a preformed mass. The preformed mass is then pressed to form a fused, texture-created structure. The surface covering products made from the process of the present invention have unique geometric patterns with well-defined grout lines or irregular decorative designs.

Title: Method and apparatus for remotely calibrating a phased array system used for satellite communication
Inventor: SILVERSTEIN SETH D
IPC: H04B17/00
Filed: 1996-06-27
Abstract: A method and apparatus for remotely calibrating a system having a plurality of N elements, such as a phased array system, is provided. The method includes generating coherent signals, such as a calibration signal and a reference signal having a predetermined spectral relationship between one another. The calibration signal which is applied to each respective one of the plurality of N elements can be orthogonally encoded based on the entries of a predetermined invertible encoding matrix, such as a binary Hadamard matrix, to generate first and second sets of orthogonally encoded signals. The first and second sets of orthogonally encoded signals and the reference signal are transmitted to a remote location. The transmitted first and second sets of orthogonally, encoded signals are coherently detected at the remote location. The coherently detected first and second sets of orthogonally encoded signals are then decoded using the inverse of the predetermined invertible encoding matrix to generate a set of decoded signals. The set of decoded signals is then processed for generating calibration data for each element of the system.

Patent CA-2200812-A1 (CA)
Title: Optimizing compilation of pointer variables
Inventor: ARCHAMBAULT ROCH GEORGE
IPC: G06F9/45
Filed: 1997-03-24
Abstract: Effective use of optimizing techniques during compilation is difficult in programs that make liberal use of pointers or indirect function calls. The indirection often means that the compiler cannot precisely determine the set of objects pointed to by a pointer at a specific location in the program, and therefore cannot efficiently eliminate pointer redundancies in the code. The present invention provides an optimising method that reduces the size of alias sets associated with program pointers. During an initial compilation phase, intraprocedural information about pointer variables referenced in each function of the program is gathered and saved in a data structure called the pointer alias graph. In the middle phase, the pointer alias graphs from all the compilation units for the program are combined to form a universal pointer alias graph and then transitive closure is performed on the universal pointer alias graph to produce a reduced graph containing the list of objects that each pointer variable can point to. In the final phase, all the files are re-compiled using the universal pointer alias graph as input, resolving all occurrences where pointer variables are de-referenced.

Abstract: A sterile drape assembly in-cludes a sheet of sterile drape material (17) bonded to a disk-like member (19). The drape estab-lishes a sterile field atop a surgi-cal slush machine (10) and is con-formable to a cooling basin (11) to provide a drape container imper-vious to the sterile slush medium.  The disk-like member is prefer-ably bonded to the bottom of the drape container and is engageable by a movable member (29) projecting into the basin. The mov-able member (e.g., a longitudi-nally reciprocable vertical shaft) moves the member and the drape to dislodge frozen pieces of the sterile medium that attach to the sides of the drape container.
