Abstract: A method of cyclically accelerating an electric motor for example for use during an agitation cycle in a laundry machine. A desired speed, direction of rotation and acceleration time is set and power is applied to the motor in a series of incremental steps, each successive step corresponding to an increase in the level of power applied during the previous step. The steps are initially estimated to be sufficient to enable sufficient energy to be supplied to the motor for it to reach the desired speed in the acceleration time. The speed of the motor is monitored and the steps of accelerating the motor are repeated with the series of incremental steps adjusted to adjust the supply of energy to the motor dependant on the speed reached in the acceleration time of the previous cycle.

Title: Apparatus and method for maintaining cache/main memory consistency
Inventor: PATEL BHIKOO J
IPC: G06F12/08
Filed: 1990-03-28
Granted: 1998-08-25
Abstract: A write-through cache (14) wherein for write operations of less than a word in length the write data stored within a FIFO memory device (18) associated with a first bus agent reflects the result of a read/modify, write ty pe of access wherein a byte or half word has been merged by a local processor (12) with a cache word. Memory control lines driven to a system bus (20) indicate to a memory controller (22) that a write operation is to be accomplished as a word write, thereby eliminating the additional time required to achieve a read/modify/write memory controller cycle. To prevent the occurrence of a problem wherein another bus agent, such as another CPU or an I/O device, writes to a system memory (24) during an interval of time that the word of data is temporarily buffered within the FIFO there is provided circuitry for detecting an external write made to the system memory. Circuitry is also provided for detecting that the FIFO has data stored within and for changing the memory command lines to indicate, instead of a word write, a byte write of a half word write operation.
Patent CA-2071173-C (CA)
Inventor: WATKINS MICHAEL I
IPC: G01N33/53
Filed: 1992-06-12
Granted: 1999-05-25
Abstract: Denaturing agents used to pretreat test samples for immunoassays are neutralized and deactivated by the addition of a treatment agent which is a combination of a buffering agent in acid form and an agent for converting the sulfhydryl groups of the denaturing agents to a non-active form such as disulfides or alkylthio groups.  The treatment agent serves this function without having sufficient denaturing activity by itself to interfere with subsequent steps of the assay procedure.  Also disclosed is a protocol for a vitamin B12 assay which involves a sequential rather than competitive binding of the B12 with excess intrinsic factor followed by the binding of excess enzyme-labeled B12 to any remaining intrinsic and immobilizing such intrinsic factor on a solid phase.  Various problems associated with B12 assays are avoided by this technique.

Title: Carrier phase recovery for an adaptive equalizer
Inventor: PAIK WOO H
IPC: H04L25/03
Filed: 1992-07-15
Granted: 2000-09-19
Abstract: A method and apparatus are provided for adaptively equalizing data signals in a communications receiver. An unequalized data signal is demodulated. The demodulated data signal is filtered in an adaptive equalizer that initially updates adaptive filter coefficients using error signals derived from a first algorithm. A carrier lock signal is generated when a phase error of a filtered signal output from the adaptive equalizer reaches a threshold value. The adaptive filter coefficients are updated using error signals derived from a second algorithm instead. of the first algorithm in response to the carrier lock signal.    The first algorithm is a self-recovering equalization algorithm such as the Constant Modulus Algorithm. The second algorithm can be a decision directed algorithm. Carrier phase is recovered without the use of a phase rotator or phase derotator, by locating the adaptive equalizer inside of the carrier recovery loop. The invention is particularly adapted for use in the recovery of multilevel amplitude modulated data, such as QAM data.
