The present invention provides a method of operating an infrared drip sensor in an enteral pump system to reduce false alarm conditions. The method consists of the following steps: optically coupling a infrared beam emitter with an infrared beam detector along an infrared beam path that extends through a drip chamber and intersects the drip path; monitoring the output signal of the infrared beam detector to detect pulses; monitoring the pulses for an interruption thereof; and running an infrared beam power update routine when an interruption is detected in the pulses, the infrared beam power update routine consisting of incrementally increasing a power level of the infrared beam until the power level of the infrared beam is sufficient to re-establish an output signal at the infrared beam detector.

A system for a motor vehicle for detecting driving conditions on a road, including a nebulosity, the range of visibility in the presence of a nebulosity or the distance between an obstacle in the road and the motor vehicle. The system includes a headlight which emits a visible light beam and an infrared light beam, at least one light sensor which receives at least a portion of the infrared beam reflected back to the vehicle, a optical device for directing at least a part of the reflected infrared beam to the light sensor and a device for detecting the modulated signal of the reflected infrared beam and determining at least one driving condition based on a comparison of the reflected infrared beam modulated signal and the corresponding emitted infrared beam modulated signal.

An electric or electronic animal trap with a CPU-controlled, rearming, multiple killing plate configuration and automatically resetting interruptible beam sensor for triggering a high voltage cycle. A high-voltage output circuit is connected to killing plates which are activated with a high-voltage pulse train when a pest interrupts the beam signal, such as an infrared beam signal generated by an infrared transmitter to an infrared receiver. The trap is preferably configured to automatically rearm if the IR beam signal is no longer interrupted after the killing cycle. If the IR beam signal is still blocked after the killing cycle, however, the trap enters a standby mode indicating trap servicing is required to remove the dead rodent from the trap.

An optical transmitter for performing high-rate data communication by means of optical space transmission is provided, which can reliably perform optical axis adjustment manually and visually, and can prevent a device from being made large in size and manufacturing cost of the device from being increased by using an simply-constructed optical transmitter. Thus, the optical transmitter of the present invention comprises an incident beam restriction section operable to allow only a visible beam which is emitted by a terminal located within a range in which an infrared beam is emitted and incident thereon to pass therethrough, a reflection section operable to reflect the visible beam which has passed through the incident beam restriction section, and a light source operable to emit the infrared beam to pass through the reflection section according to a data transmission request signal from the terminal.

The simulator of the invention is based on a number of functional units connected directly or remotely to the central computer for controlling the operation and recording the shooting results. The weapon unit is untethered and includes a real hand gun equipped with a snap-on emitter unit to send simultaneously two beams of light upon pulling the trigger—a wide angle infrared beam and a narrowly focused and aimed at the target light beam. The infrared beam is registered by the sensor near the screen and a signal indicating a firing event is sent to the computer. The light beam, preferably from a laser source is sent towards the screen, reflected therefrom towards the optical block and travels through a number of fixed and rotating mirrors and through a light divider to the light sensor. That sensor when activated sends the HIT or MISS signal to the computer. Importantly, the optical travel path of the reflected from the screen light beam coincides with the travel path of the light beam generating the target of the screen. Controlled by the computer, rotation of the rotating mirrors both places the target at a specific area of the screen as well as allows accepting of the light beam from the screen by the light sensor. The target generator allows to position the target on the screen in any desirable area or to move it with constant or variable speed along a predetermined complex path on the screen. A video projector allows adding of the pre-recorded of virtual computer-generated surrounding scene onto the screen to increase the degree of realism of the shooting exercise.

A detection warning system for caregivers in a home alerting a caregiver when a person exits a room, bed or walk through a doorway. This system comprises of two enclosures and an external reflector. A portable infrared emitter detector enclosure houses an emitter with a narrow, infrared beam, detector and transmitter. A portable receiving enclosure houses a receiver with an adjustable audio alarm. An emitter in the emitter detector enclosure emits an infrared beam to the reflector, which reflects the beam back to the detector. The detector senses when the beam is obstructed from reaching the reflector and energizes the transmitter. The transmitter receives the signal from the transmitter activating the adjustable audio alarm alerting a caregiver.

The invention discloses a system for compensating for an RF amplitude and phase error of an antenna array, and the system comprises an RF target simulation device, a vector network analyzer, a main control computer, a three-axle rotary table, an RF calibration device and an RF infrared beam combination device. The RF target simulation device consists of an antenna array, a matrix switch, a targetcontrol computer, a signal source, an attenuation module and a phase shift module, and is used for generating the simulated target scattering RF signal features. The RF signal outputted by the signalsource is divided into two ways: one way is received by the attenuation module, and the attenuated signal passes through the phase shift module, and then passes through the matrix switch to select a transmitting antenna in the antenna array, and then the transmitting antenna transmits a to-be-simulated RF signal; the other way is transmitted to the vector network analyzer. The system can achieve the compensation for the error caused by the amplitude and phase consistency of an RF signal of an original antenna array after various types of beam combination devices of the plate-shaped macro geometric structures are inserted into a dark room, and improves the characteristics of a working area.
