Title: Automatic gain control circuit in a radio telephone receiver
IPC: H04B7/26
Filed: 1990-10-09
Abstract: The present invention relates to an automatic gain control circuit (AGC) in a receiver for a digital radio telephone. Most of the total gain control of the received signal is accomplished in the base band frequency sections, in the I and Q branches whereof the signal amplification is controlled step by step, and only a minor part of the total gain control is performed in the RF stage. High amplification steps are formed by means of amplifiers (9a, 10a, 11a, 12a; 9b, 10b, 11b, 12b), of which the desired amplifier is activated by means of a digitally controlled (A, B) multiplexer (13a, 13b), and low amplification steps are formed by means of a resistance attenuator (14a, 14b), in which a signal of desired level is selected by means of a digitally controlled (C, D, E) multiplexer (15a, 15b). In addition, the RF amplifier (2) has two amplification levels, of which the desired amplification is selected by means of a digital control (F). By means of different digital control combinations (A, B, C, D, E, F) the entire gain control range required of the receiver can be covered.

Title: Folding display frame
IPC: G09F15/00
Filed: 1987-12-09
Abstract: A collapsible framework constructed of rods pivotally joined at their ends to hubs to form a self-standing unit when expanded and to fold into a small set of nearly parallel rods when folded. The hubs are designed to pivotally join the ends of four rods, with the plane defined by the pivot axes of one pair of opposing rods being offset from the plane defined by the pivot axes of the other pair of opposed rods attached to the same hub. A stab-connection latch locks two hubs together and secures the framework in the expanded position. Folding channel bars are attached to knobs on vertically aligned hubs by key-slots, the key-slots of one channel bar being of progressively shorter length going from the top-most to the bottom-most of the vertically aligned hubs to which the bar is attached. <IMAGE>

Inventor: SJOQUIST STEVEN E
IPC: A61N1/39
Filed: 1992-12-16
Abstract: A defibrillator/monitor (10) is disclosed employing a motion detection circuit 18 and control and processing circuit (20) that cooperatively detect motion at a patient-electrode interface. In that regard, an impedance measurement circuit (24) produces an output indicative of the impedance of the interface. This output is then processed by a number of filter elements before being analyzed by a motion detection routine (52). The motion detection routine includes subroutines (62 and 64) that compare the impedance against distinct upper and lower limits and then monitor the time at which the signal is above and below the limits. Basically, motion is indicated if the signal undergoes relatively large variations for a short time, or smaller variations for a longer time. A third motion clear subroutine (66) is used to determine when motion is no longer detected. Finally, a similar scheme (102) is employed to quickly restore the various filter elements after saturation. <IMAGE>   <IMAGE>

IPC: H04M3/527
Filed: 1993-09-16
Abstract: Equipment providing information services, whether installed near a central office or provided as part of a PBX includes a search service for generating a number of outdialing operations in an effort to reach a subscriber of the search service for a caller. A plurality of outdialing operations are initiated (66) simultaneously, sequentially, or as sets of calls in a sequence with each set including one or more simultaneously dialed telephone numbers. The numbers called may be extensions on a PBX, phone numbers within any area code, cellular phones, or any other type of number which can be reached by telephone. The caller is kept informed (128,130) of the success or failure of the outdialing operations and when the subscriber called by the caller is reached, the two are connected and any other outdialing operation is terminated. When all of the outdialing operations for one set of telephone numbers is unsuccessful, the next set in sequence is used in one or more new outdialing operations. <IMAGE>
Patent EP-0597603-A3 (EP)
Inventor: GRULA GREGORY JOSEPH
IPC: H01L21/3105
Filed: 1993-10-25
Abstract: An improved process for planarizing an isolation
trench in the fabrication of a semiconductor chip involves
replacing the photoresist material used for planarization
with a hard mask film. The hard mask material must be able
to gap fill ("planarize") narrow trenches which do not
receive a planarization block mask (or "filler mask") to
protect them during the subsequent hard mask film etch.
The hard mask film is typically conformal over large
features and thus will not be susceptible to pattern
density effects. Using the hard mask material, all active
areas/trenches appear the same after planarization,
independent of pattern density. Further, the hard mask
material may subsequently be polished so that there are no
peaks or spikes and no depressions.

Abstract: A method and apparatus for managing texture mapping data in a computer graphics system,
the computer graphics system including a host computer (15), primitive rendering hardware (12,
14) and a primitive data path (18) extending between the host computer and the primitive
rendering hardware. The host computer passes primitives to be rendered by the system to the
primitive rendering hardware over the primitive data path. The host computer has a main
memory (17) that stores texture mapping data corresponding to the primitives to be rendered.
The primitive rendering hardware includes a local texture memory (48) that locally stores the
texture mapping data corresponding to at least one of the primitives to be rendered. When a
primitive passed to the primitive rendering hardware is to be rendered, a determination is made
as to whether its corresponding texture mapping data is in the local texture memory. When the
texture mapping data corresponding to the primitive to be rendered is in the local texture
memory, the primitive is rendered using its corresponding texture mapping data from the local
texture memory. When the texture mapping data corresponding to the primitive to be rendered is
not in the local texture memory, the texture mapping data corresponding to the primitive to be
rendered is downloaded from the host computer main memory to the primitive rendering
hardware, and the primitive is rendered using its corresponding texture mapping data
downloaded from the main memory. The local texture memory map be implemented as a cache.

Abstract: An impingement freezer (1) having a zoned freezing chamber (10) in
which the temperature of each zone (22,24,26) is independently
controllable so that the temperature profile within the impingement
freezer (1) is coldest at a zone (22) adjacent the outlet and warmest at
a zone (26) adjacent the inlet (12) for maximum thermodynamic
usage of the refrigerant. Additionally, the velocity of each of the
impingement jets is independently adjustable from zone to zone so
that in the zone adjacent the entrance (12) of the freezing chamber (10),
the impingement jets can be adjusted to have maximum velocity to produce
maximum heat transfer coefficients and thereby an
acceptable rate of cooling within the impingement jet freezer (1).
Impingement jets are formed within nozzles (28-48) that are tapered
in two orthogonal directions to prevent frost build-up. Circulation
within the impingement jet freezer (1) is produced by venturi-like
devices (74-84) driven by vaporization of incoming refrigerant.
