Abstract: An improved emergency response system is provided. The system includes a patient or subscriber location database having a schedule of patient or subscriber activities. In one implementation, an emergency services server detects when the patient or subscriber is having a possible medical event as indicated by medical physiologic data transmitted from a wireless communication device proximate the patient. A third party such as a technologist and/or doctor diagnoses the patient and determines whether treatment is required. If treatment is required, a phone located remotely from the patient is used to call an emergency services first responder from a public safety access point in the patient's location. The remotely located phone has an automatic location identification database record that is updated based on the patient's current location as indicate by the patient location database.

Abstract: An optical module for an lighting fixture for providing roadway illumination. The optical module comprising circuit board having a plurality of light emitting diodes (LEDs). A reflector cups surrounds each of the plurality of LEDs, the cup comprises a narrow end surrounding the LED and a larger opening at a second end opposite the LED. A refractor lens cover comprising a plurality of molded lens, each lens positioned at the second end of the reflector cups.

Abstract: A fiber-optic acoustical sensor system includes a light source, an elongate optical cable conducting light from the light source to an optical acoustical transducer located at a distance from the light source along this cable, and a polarizer at the acoustical transducer. The sensor system includes a polarizer providing orthogonally-polarized light along the optical cable to the polarizer located adjacent to the transducer. Because of the polarizer adjacent to the transducer, disturbances of the optical cable and resulting polarization perturbations of the light transmitted along this cable do not affect the optical acoustical transducer. The acoustic transducer is responsive to sound energy to provide an optical return signal indicative of this sound energy.
