Abstract: A turret knob comprises an adjustable member, an engagement member and a plurality of stop members. The adjustable member is capable of being adjustably positionable about an axis of rotation. The engagement member is coupled to the adjustment member, and a relative position of the engagement member with respect to the axis of rotation corresponds to a position of the adjustable member as the adjustable member is adjustably positioned about the axis of rotation. The plurality of stop members are each selectably positioned about the axis of rotation. Each stop member is capable of interfering with the engagement member and blocking movement of the adjustable member as the adjustable member is adjustably positioned about the axis of rotation. The adjustable member is adjustably positionable about the axis of rotation between adjacent stop member positions.

Abstract: A circuit architecture, or topology, that provides a level shifter substantially independent of the duty cycle of an input signal includes an H-bridge arrangement of field effect transistors, a pair of capacitively coupled input terminals connected to the gates of the high-side transistors and circuitry to set the bias voltage at the gates of the high-side transistors, wherein the bias voltage generation circuitry receives at least information indicative of both the H-bridge power supply voltage and the modulation of the input signal. Various embodiments include a switchable element coupled in series with a voltage divider portion in the bias voltage generation circuitry. The ratio of on to off time of the switchable element determines the average current through the voltage divider and thus the bias voltage. To prevent excessive short-circuit current flow through the high-side transistors, the switchable elements are turned off responsive to detection of a short-circuit condition.

Abstract: Database content changes are asynchronously remotely copied from a primary site to a remote site by associating sequential identification with each respective log record write and each corresponding data record write received at the primary site. Each respective log record write is asynchronously remotely copied from the primary site to the remote site, and an acknowledgement corresponding to a log record write that has been completed at the remote site is received at the primary site. Each data record write having a sequential identification that is prior to or equal to the sequential identification of the log record write corresponding to the received acknowledgement is then asynchronously remotely copied to the remote site. A log record write is asynchronously remotely copied from the primary site to the remote site before a data record write is asynchronously remotely copied from the primary site to the remote site.

Abstract: A portable system for facilitating inclined shooting of projectile weapons comprises a ranging system, an inclinometer and a processor. The ranging system measures a line-of sight range distance from a vantage point to a target that is elevated or depressed relative to the vantage point, and the inclinometer measures an inclination angle of a line of sight between the vantage point and the target. Based on information from the rangefinder and inclinometer, the processor determines a predicted altitude-compensated inclined shooting (ACIS) trajectory at the line-of sight range distance for a preselected projectile. The ACIS trajectory is based on a bullet path height correction between a bullet path height at a first altitude and a bullet path height at a second altitude, a range distance of the target from the vantage point, and selected meteorological atmospheric information.

Abstract: A data storage subsystem that includes three data storage units, three check storage units, and an array controller coupled to the three data and three check storage units can tolerate failure of any three data and check storage units failures can be occur before data stored on the data storage subsystem is lost. Information is stored on the data storage subsystem as a symmetric Maximum Distance Separation code, such as a Winograd code, a Reed Solomon code, an EVENODD code or a derivative of an EVENODD code. The array controller determines the contents of the check storage units so that any three erasures of the data storage units and the check storage units can be corrected by the array controller. The array controller updates a block of data contained in any one of the data storage units and the check storage units using only six IO operations.

Another embodiment provides that the force magnitude is greater than a magnitude of the sensed user-applied force. Yet another embodiment provides that the force magnitude is proportional to a magnitude of the sensed user-applied force.

Metadata related to the metadata corresponding to the metadata access call from the remotely located filesystem is prefetched when the related metadata is not contained in the local filesystem cache. The metadata related to the metadata corresponding to the access call can be contained in a child node or a parent node of the node containing the metadata corresponding to the access call, or the descendants of such nodes.

The absorbing electrochromic layer is placed in the darkened state by applying a predetermined control voltage to the electrochromic device, forming the electrochromic device by dark-state deposition, or forming an electrochromic device that is in its darkened state in an equilibrium state.
