Abstract: A method is provided, for example, to implement multiplexed communication between a controller and a preamplifier in a storage device. For example, multiplexed communication is implemented by controlling a bidirectional serial data line of a digital bus to selectively transmit digital signals in either a first direction from the controller to the preamplifier or a second direction from the preamplifier to the controller, in response to a direction control signal, and concurrently transmitting a synchronous clock signal over a clock signal line of the digital bus from the controller to the preamplifier to synchronize transfer and processing of the digital signals transmitted on the bidirectional serial data line of the digital bus. The direction control signal is transmitted from the controller to the preamplifier on one of the bidirectional serial data line and the clock signal line of the digital bus.

Abstract: A method is provided to enable communication between a controller and a preamplifier in a storage device. For example, the method includes implementing a serial port which is configured to transmit digital signals between the controller and the preamplifier over a single bidirectional serial data line. The serial port is controlled to selectively transmit digital signals over the bidirectional serial data line in either a first direction from the controller to the preamplifier or a second direction from the preamplifier to the controller.

Abstract: A method is provided, for example, to implement multiplexed communication on an analog bus between a recording channel and a preamplifier in a storage device. A first input of read data circuitry within the recording channel is switchably connected to a first analog line of the analog bus to receive read data transmitted from the preamplifier to the recording channel over the first analog line during a read operation. In addition, a write data output of write data circuitry within the recording channel is switchably connected to the first analog line of the analog bus to transmit write data from the recording channel to the preamplifier over the first analog line during a write operation.

Abstract: A simulated game of Basketball that is played using an existing Basketball hoop, Basketball and specialized marked deck of cards comprising of multiple cards marked 1 2 3 4 5 6 7 8 and Wild Card. Also, the game incorporates eight bean bags numbered 1 2 3 4 5 6 7 and 8. The game is played using an existing Basketball hoop and Basketball. The scoring is determined by the points on the specialized deck of cards that corresponds to the bean bags the player shoots the ball from. The player with the highest score at the end of the game wins.

Abstract: A (e.g., hard-disk drive (HD)) system supports reader standby mode and/or writer standby mode. For reader standby mode, reader circuitry in the system's preamplifier is transitioned to a low-power mode during write operations. To provide quick transition from write mode to read mode, the reader circuitry is transitioned to pre-read mode before the end of the write operation. For writer standby mode, the preamplifier's writer circuitry is transitioned to a low-power mode during read operations. To provide quick transition from read mode to write mode, the writer circuitry is transitioned to a pre-write mode before the end of the read operation. The availability of a reader standby mode during write operations and a writer standby mode during read operations reduces power consumption as compared to HD systems that leave the reader circuitry in pre-read mode throughout each write operation and the writer circuitry in pre-write mode throughout each read operation.

Abstract: An apparatus and method for determining a head parameter value (e.g., head resistance) of a resistive head. A test head current is supplied to the head during a head parameter measurement interval using the same current sources that supply a bias current to the head during an operating (read operation) interval. The determined head parameter value is latched for use in setting the control loop gain for a control loop that controls the current sources during the operating interval.

Abstract: A temporary snap-in, hold-down, clip includes two sets of snap-fit fingers at opposite ends of a central sleeve for the purposes of temporarily holding a mirror housing to a vehicle body panel during the vehicle assembly process. One set of snap-fit fingers engages the mirror housing and an opposite set of fingers on the clip engages the inside edge of the vehicle body panel hole which normally receives an electrical wiring tail from the mirror assembly. The locking surfaces of barb-like heads on the two sets of fingers are designed so that the clip is more securely held to the mirror housing than to the body panel. A cylindrical sleeve portion of the clip projects outwardly and extends past the mirror housing gasket interposed between the housing and the body panel. The wiring tail passes through the sleeve unless the gasket is protected from the wiring tail as the wiring tail is pulled to the side by the installer.
