Abstract: A method of determining a media class using an optical translucence sensor (OTS) in an imaging device. A media sheet for processing by a media processing device (MPD) in the imaging device passes through an OTS positioned on a media path prior to the MPD. The OTS has an output that is periodically sampled in several predefined interest zones to provide a plurality of intrinsic variables related to the media sheet. The intrinsic variables are combined with extrinsic variables to form a variables data set that is normalized then fed to a controller having a predefined set of media class determining equations for determining a media class for the media sheet. A media class determining equation is provided for each class of media expected to be used in the imaging device. The determined media class is then used to set one or more operating parameters for the media processing device.

Abstract: A computer system comprising a central processing unit (CPU), a memory circuit, an I/O coprocessor, and an input device comprising a touchpad and two joysticks positioned one to each side of the touchpad. The input device interfaces to the CPU via a serial data link to the I/O coprocessor. The touchpad has a default template graphic image inscribed on or in the touchpad surface and has a retainer for removably securing template overlays to be used with the touchpad instead of the default template.

Abstract: A computer network includes at least one host computer, at least one peripheral device, and a microprocessorless network adapter interconnecting the at least one host computer and the at least one peripheral device.

Abstract: A method and system is provided for capturing, organizing, and presenting information generated from a television program. The method monitors closed caption data of television programs for transition symbols and user defined search parameters and scheduling information. Information relating to captured television programs is entered into a capture management database for assembly into an interactive results file. The interactive results file allows a user to browse, view and navigate the captured television program information.

Abstract: A computer system for high-performance video and audio manipulations comprising a locked memory cartridge and an audio/video/compact disk (CD) drive controller/coprocessor. The computer system has a central processing unit (CPU) with at least one bus associated therewith, with the bus having at least one bus line. The cartridge comprises a readable memory, a memory control circuit, a lock control circuit, and a connector all in circuit communication with each other. The connector allows the memory, the memory control circuit, and the lock control circuit to be pluggably connected in circuit communication with the CPU. The memory control circuit scrambles some of the bus lines, thereby scrambling the data in the memory on reset, and unscrambles the bus lines responsive to inputs from the lock control circuit.

Abstract: A desktop computer system having the capability to suspend and resume the state of the computer system. The suspended system state is saved to the system hard file such that system power may be removed, effectively allowing a system suspend requiring no power from the power supply.

Abstract: A computer system comprising a central processing unit (CPU) configured to accept coordinate type data from a touchpad or the like. The CPU has an operating system executing thereon with special support for interfacing to the touchpad. The operating system has the following capabilities: (1) mapping out geometric regions of the touchpad and assign the regions to specific region identifiers responsive to application programs and (2) determining the region identifier of a touched region and passing that region identifier to the application program. Support is also provided for changing the units of the commands used to define the regions.

Abstract: An input device for a computer system is provided which translates large body part or multiple body part motion into directional data. The input device includes a rigid support member having sufficient size to accommodate use by a human being for sitting, a riser member, a connection device for connecting the riser member to the support member, a transducer device in physical communication with the riser member for sensing the riser member motion and for conveying the motion to a computer system in the form of representative electrical signals, and a resilient device in physical communication with the riser member for maintaining the riser in a predetermined position relative to the support member when the riser is not subject to external forces. The cross member may be embodied in several forms, including straight and synclinal cross members. Alternatively, a haptic sphere or disc may be employed instead of a cross member.

Abstract: The present invention provides a computer system supporting multiple, removable ROM-based applications without requiring the ROM-applications to be inserted into a particular slot. The computer system accepts one or more cartridges into any combination of slots. Once a cartridge is inserted into a slot, the computer system senses the insertion of a cartridge. The computer system then determines whether to swap the address ranges associated with the cartridge connectors, or slots. The address swap is implemented by either (i) swapping the cartridge connector chip selects or (ii) performing a page swap with the memory management unit.
