摘要： An improved apparatus for rapidly compressing, expanding, and displaying broad band information which is transmitted over a narrow band communications channel. In the preferred embodiment, a video image is cyclically assembled in low resolution and high resolution phases from digitized data representing gray level intensity for individual pixels which have been grouped into pixel. During the initial cycle of the low resolution phase, a representative sample of cell intensity values is transmitted by a sending station to a receiving station according to a video compression routine. The receiving station then uses a video expansion routine to calculate an intensity value for those pixels whose intensity values were not transmitted and displays an initial image. This image is refined during subsequent low-resolution cycles by additional transmissions from the sending station which replace the calculated cell intensity values with an actual or better approximation value for that pixel. During the high resolution phase, an error determination routine or external input from a viewer selects those pixels containing the greatest deviation in intensity levels from the input video image. The error compression and expansion routines substitute a plurality of individual pixel intensity values for previously calculated intensity values. The present invention also discloses an apparatus for allowing color capable stations to send or receive color transmissions while retaining the capability to interact with noncolor stations. Color data is compressed and interleaved with black and white data by a color capable sending station and subsequently separated and expanded by a color capable receiving station.

摘要： A workstation with multiple, functionally related displays clustered under and controlled by a common transparent overlay control device. The position of a hand-held stylus is sensed by the overlay control device and is used as a system input to control system operations, system communications and input, manipulation and editing of images displayed on the displays. Control of certain workstation operations is achieved by directing the stylus towards function symbols which are affixed to the overlay surface. Actuators or other adjustment mechanisms are provided for adjustment of the height and pitch of the workstation for the comfort of the operator. Further, the workstation provides integrated data audio communication over ordinary narrow-band telephone lines or high speed data lines with other linked workstations.

摘要： An image processing apparatus coupling at least two image processing systems connected to a network. The network couples image information to each system, and each system displays at least one image. Each system includes a communication unit and a control unit. The communication unit couples information to and receives information from the network. The control unit includes a central processing unit (CPU) and a partitioned memory space, including, both common and personal memory. The personal memory of each system contains one or more personal images that can be viewed only by the respective system, wherein each system is controlled to access only its respective personal memory. Under control of the CPUs in the respective systems, a common image is coupled to each system over the network and commonly displayed on each system. While the common image is commonly displayed on each system, it is edited by the first image processing system.

摘要： The disclosure describes improved apparatus for driving a load, such as a meter, in proportion to a source voltage produced by a signal generator. The apparatus includes a non-differential gain stage for generating an amplified voltage between a gain stage output and one of the generator outputs. The non-differential gain stage is followed by a differential stage which generates a rereferenced voltage between the differential stage output and one of the load terminals. The rereferenced voltage is proportional to the amplified voltage and is substantially independent of any offset voltage between the one generator output and the one load terminal. By coupling the rereferenced voltage to the load, the load voltage is made proportional to the source voltage irrespective of changes in the offset voltage between the one generator output and the one load terminal. The load may include a meter and an amplifying stage for ranging and zeroing the meter.

摘要： Charging voltage and current control circuits for battery chargers provide for a constant output voltage above a first predetermined value of charging current and an increasing output voltage below the first predetermined value of charging current. The charger makes use of a pulse-width modulated control circuit utilizing a variable duty cycle proportional to charging current and couples a signal proportional to charging current via a diode-resistor network to the pulse-width modulator for values below the first predetermined value of charging current. A current limit control circuit provides a current limit function by driving the pulse-width modulator to a minimum duty cycle during overcurrent conditions.

摘要： An optical position location apparatus for locating the position of an object in one or more dimensions, which relies upon one or more sources of radiant energy and distributor devices to disburse such radiant energy over a location region or window. Integrated collector assemblies positioned opposite to the distributors receive and collect the transmission of the distributed radiant energy and through reflection or refraction, transfer radiant energy to a minimum of detection locations to monitor the absence or alteration thereof. A rotating optical scanner and a detector are utilized with a continuous stationary light source to successively monitor specific location-coordinate-related portions of transmitted radiant energy and through electronic circuitry, a signal is developed to disclose, with accuracy, the location of objects within the location region "window", as well as other parameters including object size. In other embodiments, an apparatus with elements cooperating along two dimensions is capable of yielding three-dimensional object parameter information.

摘要： Charging voltage and current control circuits for battery chargers provide for a constant output voltage above a predetermined value of charging current and a step-wise increased output voltage below the predetermined value of charging current. The charger makes use of a pulse-width modulated control circuit utilizing a variable duty cycle to control charging current and couples a trim command signal responsive to a primary side signal representative of charging current to the pulse-width modulator for values below the predetermined value of charging current. A current limit control circuit provides a foldback current limit function by driving the pulse-width modulator to a reduced output current during overload conditions.

摘要： A miniaturized bowling ball game comprising a simulated lane assembly having an automatic pin status indication, a scoring readout device and a noise generator operated responsive to a ball propelled over the lane assembly by an aimable shooter striking operating contacts simulating the ball striking and knocking down pins. The scoring read out device not only provides the score, but also the frame, and indicates if the prior frame resulted in a spare or strike. Electronically generated noises simulate the noises that occur when pins are knocked down in an actual bowling ball game. Also, the electronic controls randomly provides data which results in different scores, even though balls traverse the same routes.

摘要： A hand-held electronic game which uses a two-way mirror arrangement to simulate the battle between the player's rocket ship protected by barriers and a plethora of enemy rocket ships. The enemy rocket ships and the barriers are affixed on two parallel, spaced apart, vertical planes. Apertures in the front plane give the impression in the two-way mirror that the devices on the different planes are all in the same plane. In addition, the player's rocketship and death ray, on a horizontal plane, are also projected on the two-way mirror so that it appears that all the devices are in a single plane.
