Abstract: A device, a method and a system for providing control of access to data which is stored in an electronic data storage device. The device, method and system enable various types of permissions to be set for determining access to the stored data, such that if an attempt is made to access particular data which does not have a suitable permission type, access is denied. Preferably, the present invention is implemented as an access control device, such as a chip for example, which more preferably controls all access to the data storage device. This implementation is preferred, since such electronic devices are more difficult to “hack” for access by an unauthorized user.

Abstract: The present invention is a snowplow diagnostic and connection system for connecting a snowplow to a vehicle. The system includes an diagnostic circuit and an indicator which detects and indicates the status of various components of the snowplow and its controls. The indicator includes a specific indication of the status of each detected subsystem or each component, as well as providing a general warning if any problem is detected. The indicator has a plurality of LED's which individually represent the various subsystems or components. If a problem is detected with any of the subsystems or components, the vehicle's headlights are caused to flash, thus alerting the operator.

Abstract: A portable communication apparatus has a microphone (14) and a processing device (31) with an input (37) operatively coupled to the microphone. The processing device generates a digital output signal from a first electric signal received from the microphone. A reading device (17; 52) in the portable communication apparatus generates a second electric signal from an optical or magnetic input signal. The processing device (31) is operatively coupled to the reading device (17; 52), so that the second electric signal from the reading device may be received at the input (37) of the processing device.

Abstract: A retractable antenna for a wireless communicator includes an elongate radiator that slides through a helical radiator. An electrical contact alternately contacts one of the elongate radiator and the helical radiator depending on a position of the elongate radiator relative to the helical radiator. Mechanical disengagement is accomplished by the movement of the elongate radiator into a contact position with the electrical contact to disengage the helical conductor. A preferred feature of the antenna is that one of the helical radiator and elongate radiator make electrical contact with the wireless communicator circuits, even when the antenna is placed between a fully retracted and fully extended position. Multiple band operation is another feature of the retractable antenna due to its periodic nature. Ease of assembly is achieved through individual snap fit components.

Abstract: Digitalized video images are compressed in several steps in order to provide a system for transmitting moving video pictures via narrow band channels, such as the telephone network. The system is based on any extension of the bit-plane coding technique to video sequences and lossy conditions. The compression technique can also be advantageously used in a lossless compression system. The system involves the steps of bit plane representation and skipping the least significant bit plane(s), shifting the pixels, coding with a Gray code, the use of segmentation, and motion-estimation/motion compensation and application of a transmit/not transmit/motion compensate (TX/NT/MC) procedure, exploiting of the temporal redundancy of two corresponding bit planes via an XOR operation on two successive images, and a plane-by-plane application of an extended RLEID technique.

Abstract: A projectile to be fired from a weapon barrel includes a projectile body and a plurality of stabilizing wings circumferentially distributed about a rearward portion of the projectile body. A pin pivotally attaches each stabilizing wing to the projectile body for pivotal motion about a pivot axis to assume a folded state and an outwardly pivoted, deployed state. In the folded state of the stabilizing wings the center of gravity of the respective stabilizing wings is at a greater radial distance from the longitudinal axis of the projectile body than the pivot axis. A gliding body is releasably mounted on each stabilizing wing. Each gliding body has a wing-shaped extension for contacting an inner surface of the barrel in the folded state of the stabilizing wings as the projectile travels in the barrel upon firing.

Data from the first computer device is processed by second computer device to calculate the ration of feed for the shed for a predetermined time interval to maintain optimum productive weight of the birds. A control device activates the feeding system at a predetermined time to supply the determined ration of feed.

Abstract: A frangible insert that is inserted in a pre-positioned bushing in the wall of a manhole form from the convex, easily reached side of the inner form wall. A key in the insert is received in a keyway in the bushing in the form wall so that the insert is properly oriented in the form. Concrete is then poured into the form, enveloping and affixing the insert within the man hole wall. A weakened, frangible region is provided on the insert in a position immediately adjacent to the form wall so that after the concrete is cured, the manhole and form can simply be separated, causing the portion of the insert embedded in the concrete to separate from the insert portion in the form bushing.

Abstract: A locking mechanism adapted to be placed in locked and unlocked positions. The locking mechanism includes a lock-bolt mounted for movement between locked and unlocked positions and a first engagement element having disengaged and engageable positions. An electric actuator having a movable output drives the first engagement element to the engageable position. A manually operated second engagement element can be engaged with the first engagement element in its engageable position. A lock-bolt drive mechanism is operatively coupled between the lock-bolt and the first engagement element. A slidable element responds to a movement of the manually operated second engagement element and slides linearly between engaged and disengaged positions. The slidable element cooperates with the lock-bolt drive mechanism to enable manual movement of the lock-bolt between the locked and unlocked positions thereof such that the disengaged position of the slidable element corresponds to the locked position of the lock-bolt.
