  • Patent number: 9123222
    Abstract: An infra-red motion detector for monitoring motion in a monitored space is described. The motion detector includes, within a housing, an infra-red radiation sensor sensitive to infra-red radiation incident through a window. A refractive optical system within the housing selects incident infra-red radiation for redirection onto the infra-red sensor. An external light source mounted externally of the housing directs external light through the window providing a recognizable light input. A refractive Fresnel patch mounted externally to the window selects incident light from the external light source and redirects it to a tamper sensor within the housing. A detection controller processes signals output by both sensors in monitoring the space. The detection controller detects incident light from the external light source and trips a tamper alarm in failing detection, and further detects changes in infra-red radiation in the monitored space and trips an intrusion alarm upon detecting changes.

    Abstract: A system for detecting intrusion across a surface, comprising a plurality of light sources projecting an array of illuminating beams along different optical paths in the surface and a detector array system directed such that it detects along a plurality of fields of view in the surface, illumination reflected from the illuminating beams. A signal processing system detects changes along the array of fields of view, in the reflected illumination level detected by the detector system. An increase greater than a predefined level in the reflected illumination level from any field of view provides an indication of an intrusion across the surveilled surface along that field of view, at the crossing point of the direction of that field of view with the optical path whose illuminating beam generated the increase in reflected illumination from that field of view.

  • Patent number: 8624526
    Abstract: A sensing device, for controlling an LED lighting equipment, and more especially for electrical connection with at least one LED lighting equipment that can be driven by a DC power supply, is disclosed. The sensing device, which can be supplied with an external DC power source, comprises a control module, a signal adjusting unit, an object detecting unit, and a manual time-delay adjustor. The control module can send a control signal train of PWM or PFM to the signal adjusting unit, which will in turn send an amplified signal train of PWM or PFM to the LED lighting equipment, so as to control the illuminating level of the equipment. Thus, the problems of the conventional light modulators, resulting from the use of an AC power supply, can be alleviated. Also, the associated cost of the equipment can be reduced.

  • Patent number: 8584345
    Abstract: Because reprocessing or refurbishing of physiological sensors reuses large portions of an existing sensor, the material costs for refurbishing sensors is significantly lower than the material costs for making an entirely new sensor. Typically, existing reprocessors replace only the adhesive portion of an adhesive physiological sensor and reuse the sensing components. However, re-using the sensing components can reduce the reliability of the refurbished sensor and/or reduce the number of sensors eligible for refurbishing due to out-of-specification sensor components. It is therefore desirable to provide a process for refurbishing physiological sensors that replaces the sensing components of the sensor. While sensing components are replaced, generally, sensor cable and/or patient monitor attachments are retained, resulting in cost savings over producing new sensors.

  • Patent number: 8542109
    Abstract: An intrusion detection system that provides foliage penetration is disclosed employing an array of field disturbance transceivers operating at UHF frequencies. The array of transceivers generate a multiplicity of electromagnetic wave fields between nearby units and detect the presence of intruders by detecting disturbances in these fields. The emitted UHF signals used to generate the electromagnetic wave fields are also used to provide the communication link between transceivers in the array and to a control station. The control station facilitates the operation of the array from a remote monitoring site. A unique method of array deployment provides multiple opportunities to detect an intruder and secondarily provides redundant communication links in case of a sensor failure. Automatic means of setting detection thresholds based on environmental conditions assures a high probability of detection along with a low false alarm rate.

  • Patent number: 8508366
    Abstract: A method of identifying a potential security threat in a space. A first scan of the space is performed during a first time interval by illuminating at least a portion of the space with energy from an energy source at an illumination angle, such that the energy is reflected from a surface in the space. An incident angle of the reflected energy is detected with a detector located at a known distance from the energy source and a distance from the surface to the energy source is calculated based on the incident angle. The steps are repeated for a plurality of different locations in the space. A first map of the space is generated from the first scan, and a second map is generated from a second scan of the area. The maps are compared to determine a change in the space and to determine if a potential security threat is present.
