Title: Fail-safe brake actuation system
Inventor: RICHARD ARTHUR L
IPC: B60T13/74
Filed: 1995-05-31
Granted: 1999-03-30
Abstract: The actuator uses an electric motor to drive a recirculating ball screw thread connection, to hold a brake-actuation spring at bay. After the spring has been compressed to the brakesoff position, the electric motor is de-energized. Then, the screw-thread connection is prevented from rotating and backing off, by virtue of the fact that the electric motor is connected to the screw thread via a high-reduction worm gearbox, which will not reverse-drive. An electric clutch is included between the screw-thread connection and the gear-box, the clutch being held, electrically, in the locked or drive condition while the brake is required to be held off. The brake is applied by releasing or de-energizing the clutch to the non-drive or free condition.

Title: Method and apparatus for communicating data between medical devices to improve detectability of errors
Inventor: ARMSTRONG RANDOLPH K
IPC: A61N1/372
Filed: 1994-06-02
Granted: 2000-09-05
Abstract: A method and apparatus for processing data to be communicated between an implantable medical device and an external medical device to improve detectability of communication errors. An encoded block of data including message data and redundant data is processed by converting alternating data values of either the message data or the redundant data to respective complement data values. The altered block of data is communicated using relative pulse position modulation. The combination of alternating original and complement data with relative pulse position modulation (RPPM) takes advantage of the opposing adjacent errors characteristic of RPPM to decrease the probability of communication errors occurring in combinations that are undetectable by the decoding of the block of data.

Abstract: A method for testing and determining the alloy class of an aluminum alloy may be simply and easily carried out, for unequivocally determining the correct alloy class among the aluminum alloy classes 2XXX, 5XXX or 6XXX, and 7XXX, of the test sample. According to the method, the material sample is dissolved in hydrochloric acid (HCL) to prepare a first solution, then nitric acid (HNO3) is added drop-wise to the first solution in order to cause oxidation of any insoluble copper (Cu) therein and form a second solution, then a potassiumhexacyanoferrate (II) solution (K4[Fe(CN)6]) is added to the second solution to bring about a discoloration and precipitation reaction and form a final resulting solution. Finally, the applicable alloy class of the tested material sample is determined by visually categorizing the color and precipitation state of the resulting solution. A brown cloudy solution indicates a 2XXX alloy, a gray-green cloudy solution indicates a 7XXX alloy, and a blue or green transparent solution indicates a 5XXX or 6XXX alloy.

Abstract: A partial error check value for all preceding data in a sector is updated ea ch time a new data item is written into a buffer (122) during a transfer from a host computer (110) to a system storage device (116 ). The partial error check value is written into a buffer location following the location containing the most recently buffered data item from the associated sector. After the entire sector has been transferred the final check value for that sector will be available. Upon readback of a sector from the storage device (116), the sector size is longer by one data item since the appended check value is treated as the last data item. When the sector is read back, the check value is updated with the entry of each data item. When the access is complete, th e stored check value is compared with the newly calculated value to determine whether an error has occurred.
