Title: Porcine spinal cord cells and their use in spinal cord repair
Inventor: DINSMORE JONATHAN
IPC: A61K35/30
Filed: 1999-06-25
Abstract: Porcine spinal cord cells and methods for using the cells to treat spinal cord damage due to neurodegeneration resulting from spinal cord injury and neurodegenerative disorders are described. The porcine spinal cord cells are preferably embryonic spinal cord cells obtained from select gestational days.  The porcine spinal cord cells can be modified to be suitable for transplantation into a xenogeneic subject, such as a human. For example, the porcine spinal cord cells can be modified such that an antigen (e.g., an MHC  class I antigen) on the cell surface which is capable of stimulating an immune response against the cell in a xenogeneic subject is altered (e.g., by contact with an anti-MHC class I antibody, or a fragment or derivative thereof) to inhibit rejection of the cell when introduced into the subject. In one embodiment, the porcine spinal cord cells are obtained from a pig which is essentially free from organisms or substances which are capable of transmitting infection or disease to the recipient subject. The porcine spinal cord cells of the present invention can be used to treat spinal cord damage due to neurodegeneration in the spinal cord of a xenogeneic subject (e.g., a human having spinal cord injury, amyotrophic lateral sclerosis or multiple sclerosis) by introducing the cells into the spinal cord of the subject.

Title: Grade speed control and method for railway freight vehicles
Inventor: HART JAMES E
IPC: B60L15/20
Filed: 2001-04-11
Abstract: A grade speed control system and method for a railway freight vehicle can include a microprocessor receiving input from, for example, the dynamic and independent brakes on the locomotive, and the brakes on each rail car. The microprocessor can store values for desired train speed and actual train speed as well as constants and equations for converting raw data to derive brake cylinder pressure adjustments for implementing train speed control functions. The grade speed control system can also include communicate with brake cylinder control devices on articulated rail cars to increase or decrease the brake cylinder pressures to control the train speed. If actual speed differs from target speed by more than a predetermined amount, a target acceleration can be calculated and brake cylinder pressures adjustments can be derived to achieve the target acceleration to bring the actual speed of the train to the target speed in a reasonably brief time period. This sequence can be reiterated as the train progresses down the grade, automatically adjusting train braking effort as required to maintain the target speed within a tight range.

Title: Converting short branches to predicated instructions
Inventor: MOORE CHARLES ROBERTS
IPC: G06F9/32
Filed: 2001-09-07
Abstract: A microprocessor and method of processing instructions therein are disclosed.  Initially, a sequence of instructions is dispatched by a dispatch unit of the microprocessor. A code sequence recognition unit (CSR) is configured to detect a short branch sequence within the sequence of instruction, where the short branch sequence includes a condition setting instruction, a conditional branch, and at least one additional instruction that is executed if the conditional branch is not taken. The short branch sequence is then internally converted to a predicated instruction sequence that includes the condition setting instruction and a predicated instruction corresponding to each additional instruction in the short branch sequence. The predicated instruction sequence is then executed in at least one functional unit of the processor. Detecting the short branch sequence may include calculating the relative branch address associated with the conditional branch instruction and comparing the relative branch address to a specified maximum. In one embodiment, the received sequence of instructions may be converted into an instruction group by the processor. In this embodiment, the specified maximum number of instructions in a short branch sequence may be a function of the number of instructions in an instruction group. In an embodiment where the conditional branch statement is preferably allocated to the last slot of the instruction group, the additional instructions in the short branch sequence are located in the next subsequent instruction group. Converting the short branch sequence to the predicated instruction sequence may include converting each additional instruction in the short branch sequence to an analogous predicated instruction. In one embodiment, converting each additional instruction to its analogous predicated instruction includes determining a predicated instruction opcode for each additional instruction in the short branch sequence by adjusting the opcode of each additional instruction by a predetermined offset. In another embodiment, the opcode conversion may be accomplished with an opcode lookup table.

Abstract: Players obtain computer-generated barcoded sales receipts that identify bingo cards the player is to play during a bingo session. The receipts are sold at point-of-sale terminals interconnected to a bingo caller terminal that acts as a file server maintaining a database of all sold bingo cards. The server randomly generates bingo numbers, verifies all cards each time a new number is called and ends the current game when at least one winning card is detected. The bingo caller terminal computes all prizes and maintains databases of the identification numbers of winning cards and corresponding receipts, the prizes paid and the outstanding payout liabilities. The bingo caller terminal initiates a new game upon completion of the current game. Players check the status of their cards by scanning their receipts at self- service terminals upon a game's completion. Players collect winnings at cashier point of sale terminals upon submitting receipts and player-tracking cards.
