  • Compact non-linear HBT array
    Patent number: 6803643
    Abstract: HBTs in an HBT array are configured non-linearly, i.e., staggered, thus reducing the impact of thermal coupling between adjacent HBTs in the array and bypassing the minimum collector-to-collector spacing design rules required for a linear HBT array. Using this non-linear configuration, adjacent HBTs are misaligned with respect to each other. In a preferred embodiment, adjacent HBTs in the array are configured in a corner-to-corner arrangement, and in a more preferred embodiment, the collectors of the adjacent HBTs are aligned or are common, i.e., the collector of one HBT is shared with the collector of an adjacent HBT. In a most preferred embodiment, the HBTs are ballasted in an emitter-ballast/base-ballast pattern (referred to as “mixed ballasting” or “dual-ballasting”).

  • Increasing performance of planar inductors used in broadband applications
    Publication number: 20040189422
    Abstract: Increasing performance of planar inductors used in broadband applications is described. In one implementation, an apparatus includes a high Quality factor (Q) value spiral planar inductor etched directly into a printed circuit board. A ferrite structure is attached to the printed circuit board and located in proximity to the high Q value spiral planar inductor. The ferrite structure increases the Q of spiral planar inductors, but without the inconvenience and expense of a wire wound terroidal inductors. Various shaped ferrite structures may be used in conjuction with the spiral planar inductors. Additionally, in certain implementations, the ferrite structures are configured to rotate about axis permitting the inductors to be tuned, even after components have been installed on a printed circuit board.

  • Data storage device with full access by all users
    Publication number: 20040193744
    Abstract: A peripheral device of a host computer includes a microcontroller and two virtual devices. The first virtual device passes, to the microcontroller, commands of a first command set from any user of the host computer and preferably also commands of a second command set from only privileged users of the host computer. The second virtual device passes, to the microcontroller, commands of the second set from any user of the host computer. In one physical implementation of the invention, the two virtual devices are implemented as separate physical devices, and the second device is connected to an interface to the host computer only if the user is not privileged. In another physical implementation of the invention, the two virtual devices are implemented in a common physical device, and a sector of a memory of the peripheral device is reserved for handling commands of the second set from non-privileged users.

  • Radio transceiver on a chip
    Publication number: 20040192223
    Abstract: An entire radio transceiver can be completely integrated into one IC chip. In order to integrate the IF filters on the chip, a heterodyne architecture with a low IF is used. A single, directly modulated VCO is used for both up-conversion during transmission, and down-conversion during reception. Bond-wires are used as resonators in the oscillator tank for the VCO. A TDD scheme is used in the air interface to eliminate cross-talk or leakage. A Gaussian-shaped binary FSK modulation scheme is used to provide a number of other implementation advantages.

  • Robust, self-maintaining file system
    Publication number: 20040193564
    Abstract: A method of managing a data storage medium. One portion of the medium is reserved for storing data files and directories. Another, separate portion of the medium is reserved for storing allocation information related to the data in the first portion. Upon beginning a change of one of the data files or directories in the first portion, that data file or directory is flagged robustly until the change is completed. As needed, for example when the medium is mounted on a host system, the incomplete changes to the flagged data files and directories are undone or completed.

  • Methods of sanitizing a flash-based data storage device
    Publication number: 20040188710
    Abstract: A data storage device includes one or more non-volatile, blockwise erasable data storage media and a mechanism for sanitizing the media in response to a single external stimulus or in response to a predetermined physical or logical condition. Optionally, only part of the media is sanitized, at a granularity finer than the blocks of the medium. Setting a flag in an auxiliary nonvolatile memory enables an interrupted sanitize to be detected and restarted. Optionally, a “death certificate” verifying the sanitizing is issued. Preferably, the media are configured in a manner that allows atomic operations of the sanitizing to be effected in parallel.

  • Stabilization of dielectric used in transmission line structures
    Publication number: 20040182598
    Abstract: Stabilization of dielectrics used in transmission lines is described. In one implementation, the transmission line includes an outer conductor, a center conductor, and a dielectric material. The dielectric material separates the outer conductor from the center conductor. The center conductor has a conductive surface with a pattern distributed thereon. The pattern is configured to prevent the dielectric material from moving when the transmission line is exposed to an extreme temperature fluctuation. The pattern increases a coefficient of friction between the center conductor and dielectric material sufficient enough to prevent undesired motion of the dielectric material. In one implementation, the pattern includes indentations that are generally, but not necessarily limited to between 0.001 and 0.004 of an inch deep.
