Abstract: The problem of penetrating through nets and other objects is solved by cutting the object using concentric cutters in which a rotatable cutter having floating teeth rotates concentrically about a stationary cutter having fixed teeth. The object is cut by a severing action caused by the floating teeth of the rotatable cutter sliding against the fixed teeth of the stationary cutter. Embodiments of the invention include a UUV system for penetrating through fishing nets and other objects, concentric cutting assemblies for use in the UUV system and other systems, and a method for penetrating through fishing nets and other objects. A UUV system in accordance with an embodiment of the invention has a concentric cutting assembly at the forward end and a propulsor at the aft end. The concentric cutting assembly integrates seamlessly within the UUV housing and is deployed from the forward end of the UUV, enabling the UUV to quickly and efficiently penetrate through objects blocking its path.

Abstract: A cellular communications device for communicating over a cellular network control channel of a cellular mobile radiotelephone (CMR) system. A transmitter can transmit a data message formatted to correspond to an identification signal transmitted by a cellular radiotelephone when that device identifies itself to the CMR system. The data message contains selected data and is transmitted via the reverse overhead control channel of the cellular network control channel. A receiver can receive command signals from a mobile switching center of the CMR system via a forward overhead control channel (FOCC) of the cellular network control channel. A controller controls operation conducted by the transmitter and the receiver.

Abstract: A system for communicating data via a cellular network control channel of a cellular mobile radiotelephone system. The system includes a mobile switching center operable for receiving a registration signal from a registering cellular communications device. The registration signal includes identification information associated with the registering cellular communications device and a predefined data field containing data. The mobile switching center detects the presence of the identification information in the registration signal. In response to the identification information, the mobile switching center determines whether the registering cellular communications device is a member of a predetermined class of cellular sources, such as a class known as "roamer" units.

Abstract: A data messaging method for communicating a short data message between a message sender and a message recipient using the existing facilities and capabilities of the public switched telecommunication network and without establishing a telephonic connection therebetween, thereby reducing the time and cost required to communicate a data message between the parties as compared to current methods. In a preferred embodiment, the method communicates a user-definable data message between a message sender having telephone terminal equipment and a plurality of telephone lines associated therewith, and a message recipient having telephone terminal equipment and a telephone line associated therewith. According to the method, a first plurality of data message portions are associated in one-to-one correspondence with the message sender's plurality of telephone lines. The data message is then parsed into a second plurality of data message portions taken from the first plurality of data message portions.

Abstract: A system for communicating location data regarding the present service area for a "roaming" cellular paging device in a paging system. Each cellular paging device monitors a cellular network control channel to detect a cellular system identification signal transmitted by a cellular mobile radiotelephone (CMR) system. If the cellular system identification signal does not match a preassigned code for a host CMR system associated with the paging system, it responds by transmitting an identification signal to the MSC via the cellular network control channel. This identification signal includes: (1) a unique identification code that identifies the source of the identification signal, and (2) at least a portion of the system identification signal that was received by the cellular paging device. The CMR system determines that the identification signal has been transmitted by a "roaming" device associated with another CMR system and, accordingly, sends the identification signal to a verification system.

Abstract: A system for communicating data via a cellular network control channel of a cellular mobile radiotelephone system (CMR). A data message system includes reporting devices, a mobile switching center (MSC) of a CMR system, and a data collection system. The MSC receives data messages via the cellular network control channel from reporting devices operating within coverage areas of the array of cells and forwards the data messages via a first communications link to the data collection system. A paging acknowledgment system also can communicate both (1) paging messages and (2) acknowledgment messages to confirm reception of the paging messages. The paging acknowledgment system includes a communications system, remote communications devices, and at least one MSC of a CMR system. A remote communications device responds to a data message corresponding to a paging message by transmitting an acknowledgment message containing an acknowledgment code to the MSC via a cellular network control channel of the CMR system.

Abstract: A velocity compensator arrangement for a synchronizer which includes an input oscillator, main store and output oscillator in which the controlling voltage of the input oscillator is sampled during one line and compared with the controlling voltage for the next line. Any voltage difference is converted into digital form and this is stored in a digital store until the corresponding line is read out from the main store. The phase of the output oscillator is shifted in dependence on the voltage difference held in the store. This store may comprise part of the main store or be an independent store.

Abstract: A video time base corrector includes an analogue-to-digital converter for converting an incoming analogue video signal to digital form, and a store for receiving successive lines of video information in digital form from the converter. A digital-to-analogue converter converts the digital output signal from the store into analogue form.Control means are provided for writing-in and reading out the digital information into and from the store. A triggered voltage controlled input oscillator determines the rate of conversion of the analogue signal to digital form and the rate of writing into the store. An output oscillator controls the rate of reading out of the digital information from the store and the rate of conversion into analogue form.Sampling means sample the input oscillator controlling voltage during one line and measuring means detect any voltage difference in the controlling voltage during successive lines.

Abstract: A sub carrier phase shifting circuit for use in digital television equipment comprising at least two monostable multivibrators connected in cascade. The sub carrier signal is applied to the first multivibrator. Adjusting means are connected to the control inputs of each multivibrator for adjusting the monostable period of the multivibrators. On receipt of an edge of a sub carrier wave the first multivibrator is driven from a first state to a second state whereby the first multivibrator effects a change of state at its output. The first multivibrator resets to its first state after the monostable period determined by the adjusting means to give an output delayed in relation to the edge of the sub carrier wave. The delayed output causes the second multivibrator to be driven from one state to its other whereby the second multivibrator effects a change of state at its output.
