Abstract: Methods and arrangements for facilitating the integration of devices, such as hardware components, with a computer operating system or the like. Contemplated herein are self-describing devices that serve to eliminate one or more intermediate steps commonly encountered heretofore.

Abstract: There is furnished a method for providing an individual temporary access to a commonly accessible computer processing system (CA computer). The CA computer has a plurality of application programs associated therewith. The method includes the step of detecting the coupling of a portable storage device to the CA computer. The storage device has stored therein an access code for indicating whether the user is authorized to temporarily access the CA computer and information including computing preferences of the individual. It is determined whether the individual is authorized to temporarily access the CA computer, based on the access code. The CA computer is modified in accordance with the information stored in the storage device and temporary access is provided to the CA computer, when the individual is authorized to temporarily access the CA computer. The activity of at least one of the individual and the CA computer is monitored, until the storage device is de-coupled from the CA computer.

Abstract: A computer system, includes a mobile computer, a docking station for receiving the mobile computer, a bridge having a first side coupled to the mobile computer and a second side coupled to the docking station, and a flat panel display formed with the docking station for being coupled to the mobile computer via the docking station. The docking station includes a dock housing coupled to a desktop display and including a first bus, and a bridge coupled between the first bus and a second bus, the first bus residing in the dock housing and the second bus for being coupled to the mobile computer.

Abstract: A computer network system includes a plurality of computers each including a central processing unit (CPU), a memory and at least one peripheral device, a connection fabric having selectable first and second sides, the first side being coupled to a first computer of the plurality of computers and the second side being coupled to at least a second computer of the plurality of computers. Each of the first and second computers performs a negotiation to determine which one of the first and second computers controls resources of the other of the first and second computers.

Abstract: A modular computer system includes a core unit comprising a processor and a memory; a removable modular accessory; a docking connector for connecting the accessory to the core unit; and one or more subsystems contained within the accessory. The system is partitioned such that any of the cooling, power or input/output subsystems can be disposed within the modular accessory such that these subsystems can be removed from the system by removing the accessory. The core unit by itself is not useful to a user because it lacks power, cooling, or a user interface. The core unit can be connected into any of a variety of accessories and it adapts its functions to the system resources provided by each type of accessory.

Abstract: This invention describes a tunable optical filter to be used in an optical communication system. The filter of this invention has a pair of resonator cavities which are cascaded. The lengths of each of the cavities change simultaneously with the change in length of a piezoelectric sleeve which contacts a reflective surface of each of the cavities through spacers. The sleeves and spacers are set so as to move the reflecting surfaces of the cavities along a single axis in response to a single control signal. When optical signals are passed through the two cavities and when the ratio of the length of the cavities is adjusted to a predetermined ratio of integers, the resonator cavity will resonate at a desired wavelength.

Abstract: A tunable optical filter having a number cascaded resonator cavities with each cavity having electro-optic material in its interior. The resonator cavities will resonate at a select wavelength when the index of refraction of the electro-optic material is changed to a predetermined value in response to only a single control voltage. The index of refraction of the electro-optic material is adjusted to a predetermined value by application of the single control voltage to one of a pair of electrodes which are on opposite sides of the resonator cavities.
