A device which can support a determination of a camera layout by automatically preparing the camera layout that satisfies a customer request based on the customer request including a surveillance layout. Specifically, a need table that is a data set of a plurality of arrangement candidate cameras satisfying the customer request is prepared from the customer request including the surveillance layout. An arrangement of the plurality of the arrangement candidate cameras on a map is calculated based on the need table using a clustering method and a temporary layout of cameras is prepared. Then, an arrangement layout of the cameras in the surveillance layout is determined based on the temporary layout.

Various techniques are described for preventing pacemaker mediated tachycardia (PMT) within biventricular pacing systems and for detecting and terminating PMT should it nevertheless arise. In a first prevention technique, refractory periods applied to the atrial channel are synchronized to begin with a second of a pair of ventricular pacing pulses to more effectively prevent T-wave oversensing on the atrial channel. In a second prevention technique, the sensitivity of the atrial channel is reduced during T-waves also to prevent T-wave oversensing. In a third prevention technique, template matching is performed on the ventricular channels to prevent T-wave oversensing. In a fourth prevention technique, T-wave detection windows are applied to both the ventricular and atrial channels subsequent to any paced or sensed events. In a first detection technique, PMT is detected based upon a degree of variation within V-pulse to P-wave pacing intervals. In a second detection technique, PMT is detected based upon a degree variation within ventricular pacing intervals. In either case, if the degree of variation is too low, indicative of PMT, ventricular refractory periods are expanded to terminate the PMT.

The wiper device for removing foreign substances that are stuck on a windshield can include: a lever assembly, having a plurality of levers in a tournament type coupled thereto; a contact member, being supported by the lever assembly and formed in the shape of a blade in close contact with the windshield so as to wipe out the foreign substances; and a cover member, provided in a plurality, each being coupled to the lever connecting a corresponding joint of the lever assembly. Accordingly, the parts of the lever assembly having the multi joint structure are effectively covered by the plurality of cover members, allowing for a simple appearance, and since each cover member is coupled with a corresponding lever and moves with the corresponding lever in an integrated manner, it becomes possible to prevent the levers from being exposed to an outside even while the wiper device is activated.

A spread spectrum meter reading system enables the use of high power frequency hopping spread spectrum (HPSS) transmissions at both the encoder transmitter and repeater levels of the meter reading system. A plurality of end point encoder transmitter devices are each connected to a utility meter and transmit high power FHSS signals containing at least metering data for the corresponding utility meter. A plurality of intermediate transceiver units that are fewer in number than the number of end point encoder transmitter devices both receives and retransmits the high power FHSS signals. A base station includes a receiver that receives the high power FHSS signals. Preferably, the base station can receive the high power FHSS signals from both the encoder transmitter devices and the intermediate transceiver units and the intermediate transceiver units aggregates metering data from multiple encoder transmitter devices prior to block retransmission of the metering data to the base station. Preferably, the high power FHSS signals are transmitted at a maximum hopping rate of at least one minute per hop to reduce power consumption and increase battery life of the devices.

A system and method for suppressing radio frequency (“RF”) transmissions includes a transmitter for transmitting electronic signals that suppresses (e.g., prevents, disrupts, jams, interferes with or otherwise disables) RF transmissions. Some embodiments of the invention include a transmitter that suppresses one or more signals transmitted from a target transmitter in an RF transmission system to a target receiver in a wireless device operating in the RF transmission system to prevent, disrupt, jam, interfere with or otherwise disable an RF transmission between the target transmitter and the target receiver in the wireless device (i.e., target wireless device). These systems and methods may be used to interrupt communication, command and control of non-friendly combatant. These systems and methods may also be used to suppress RF transmissions to prevent the detonation of improvised explosive devices, or IEDs.

A system of satellite communications provides high throughput data transmission rates for mobile terrestrial terminals.
