Abstract: A method and system for automatically collecting and for analyzing information about time and work performed on a computer includes a hardware abstraction layer for monitoring activity on various user input devices. The system also includes the following elements: a data collector for monitoring certain portions of a user's computer activity and for logging into a log file those certain portions of a user's computer activity; a data analyzer for determining by following user-defined rules showing which portions of those certain portions of a user's computer activity constitutes continuous work activities, and how this work should be categorized by project and task with project; and an external interface for building the rules defining work. The data collector includes a resident module, such as a TSR (terminate-and-stay-resident) module, which extends the file system of the computer so that detailed records are kept of file activities.

Abstract: Digital data bits are stored at storage locations at plural depths within a holographic medium of a holographic storage disk in the form of selective, localized alterations in a format hologram. Micro-localized regions of a reflection format hologram extending throughout the medium are deleted by focusing a high-power laser beam at desired storage locations. The deletion regions have a lower reflectivity than the surrounding parts of the format hologram. Tunable-focus storage and retrieval heads, as well as dynamic aberration compensators, are used for multi-depth access. Storage and retrieval may each be achieved with a single head.

Abstract: A time and work tracker that automatically collects and analyzes information about time and work performed on a wireless device is described herein. According to the present invention, a time and work tracking function is initiated on a wireless device. Thereafter, a user begins to perform work on the wireless device. As the user works, the tracking function on the wireless device collects data relating to the activities performed by the user. The collected data is then analyzed to determine what types of work the user has actually performed.

Abstract: An apparatus for optical reading or recording information on an optical disc is rotatable about an axis of rotation. The apparatus includes a carriage, an objective lens, and an objective lens holder. The carriage has a center of mass. The carriage is movable relative to a frame along a path radial to the axis of rotation. The objective lens has an optical axis. The object lens is mounted to the objective holder so that the optical axis of the objective lens is within a first distance of intersecting the center of mass of the carriage. The holder is movable relative to the carriage so as to move the objective lens along its optical axis.

Abstract: Focusing means to focus a beam upon a reflective-transmissive surface. Reflecting means to reflect a central portion of the beam from the reflective-transmissive surface. Transmitting means to transmit a portion of the beam that lies outside the central portion. Receiving means to receive the transmitted portion of the beam and combining means to combine the reflected central portion of the beam with a test beam to generate an interference pattern.

Abstract: A method of displaying Electronic Program Guide (EPG) data in substantially a grid format, without using “channel” information as an axis. Instead of being presented by channel and time, the data is presented only by time. Thus, program information from multiple channels may be displayed in a single row. Various truncation algorithms allow program descriptions to be shortened, enabling placement of the descriptions into gaps or empty cells in an available row, whereas without the truncation the program description would not have fit into the gaps. For example, when there is a program X in the grid on a first line with at least one gap, and another program Y in the grid on a second line, where Y spans a time slot corresponding to at least one of the gaps on program X's line, either X's title or Y's title, or both, can be truncated, and Y's title can be moved to X's line.

First, an electronic storage medium tracking identifier is incorporated onto an electronic storage medium and stored on a database. Next, a package tracking identifier is situated onto a package in which the electronic storage medium is stored. The electronic storage medium is then tracked while being shipped between various entities using the tracking identifier on the package. Further, the electronic storage medium may be identified using the tracking identifier on the electronic storage medium in order to afford authorized use of the information contained on the electronic storage medium.

Abstract: Disclosed is a high-speed dynamic actuating system for optical disks, particularly useful in an optical disk drive, wherein a closed-loop approach is used to overcome the diversity between devices and thus meet the requirement for high speed track-accessing and solve the problems in that the convention open-loop track-jumping takes a long period of time to perform segmental adjustment. The pick-up head is activated by applying high-speed dynamic actuation of the lens so as to conform to the pre-determined velocity curve and eliminate the wobble of the lens caused by different track-jumping times in an optical disk drive and a hard disk. In addition, said system can be implemented in an integrated circuit (IC), which is directly controlled by the hardware and thus effectively simplifies the complicated configuration as in the prior art.

An information detection device having a detection output and a servo mechanism that controls operations on detected information is provided in conjunction with a signal summing circuit, a direct current voltage reference, a control clock connected, a servo error signal circuit having a servo error signal output and input, a sampling clock, and a processing circuit having an input connected to a digital output of the analog to digital converter and an output for controlling the servo mechanism.

Abstract: This invention provides a method to control the buffering of encoded video data organized as frames or fields. This method involves determining the picture number of each incoming decoded frame, determining the expected presentation number at any time and marking any buffer as ready when its picture number is on or after the presentation number.

Abstract: An encoder converts a binary data word to a binary code word. The encoded bits have first and second binary values at a predetermined clock interval. A pulse generator responds to the encoded bits to generate energizing pulses during each clock interval in which the encoded bits have the first binary value. The energizing pules have a uniform duration less than the clock interval. A laser responds to the energizing pulses for recording on a medium.

Abstract: A cartridge unloading apparatus for a disk drive having a cartridge loading end, a remote end, and a base plate. The apparatus is employed for tiltably unloading the disk from a spindle magnet with a peeling action. The apparatus includes first and second sliders positioned relative the ends of the disk drive. The sliders each have only one S-shaped slot formed therein. Each slider has a slot to receive one of the two lifting pins provided on a cartridge receiver. The movement of the sliders drives the lifting pins along the slots, thereby raising or lowering the cartridge receiver depending upon the direction of rotation of the tiller. The sliding motion of the lifting pins engaged in the S-shaped slots thus unloads a disk from or, alternatively, loads the disk onto the drive spindle.

Abstract: An apparatus for providing sector location pulses to a controller of a rotating disk data storage device having a counter clocked in proportion to the disk rotation rate and an accumulator for accumulating times to sectors on the disk. A comparator connected to the counter and the accumulator enables an accumulator clock for repetitive clocking of the accumulator at such times the contents of the accumulator do not exceed the contents of the counter. A sector location pulse generator connected to the comparator generates the controller pulses, when enabled, concurrently with the accumulator clock signals. A master reset generator resets the first counter and the accumulator each time an index location on the disk passes a transducer head used to read and write data to and from the disk and a partial reset generator resets the accumulator each time the transducer head is moved between tracks on the disk.
