  • Patent number: 10261114
    Abstract: Devices and methods for detecting a medical sensor device being attached to a host device are disclosed. The host device includes a reader circuit that can generate an AC pilot signal. When the medical sensor device is being attached to the host device, the AC pilot signal is fed to a non-linear circuit in the sensor device, which responds with a DC signal. The host device compares the magnitude of the response signal with a threshold magnitude. If the magnitude of the response signal is greater than the threshold magnitude, the host device determines that the sensor device is being attached and establishes connection with the sensor device.

  • Patent number: 10218218
    Abstract: An LED lighting system comprising a luminaire and an emergency backup system is used to replace a fluorescent or an LED lamp normally operated with AC mains. When a line voltage from the AC mains is unavailable, the emergency backup system is automatically started to provide a high DC voltage larger than a minimum operating voltage of the luminaire. The emergency backup system comprises a rechargeable battery, a driver configured to convert a DC voltage from the rechargeable battery into the high DC voltage when enabled, and a voltage sensing and control circuit comprising a logic circuit and a relay switch configured to enable the driver and to couple the high DC voltage to two electrical conductors of the luminaire to operate the luminaire, no risk of damaging the luminaire.

  • Patent number: 10205342
    Abstract: A system may include a light source. A converter may be configured to convert an AC voltage to a DC operating voltage during normal operation. A power backup device may be coupled to the converter. A current source may have a first terminal configured to receive the DC operating voltage during regular operation and a second terminal configured to provide a pulse-width modulated (PWM) signal to an anode end of the light source. A switching device may have a first connecting terminal coupled to the anode end of the light source, a second connecting terminal coupled to the power backup device, and a control terminal coupled to the converter. The switching device may be configured to open a switch between the first connecting terminal and the second connecting terminal during normal operation and close the switch upon detecting an interruption of the DC operating voltage at the control terminal.

  • Patent number: 10190760
    Abstract: LED lighting systems, mounting configurations, and light fixtures are disclosed for original and retrofit configurations. Some configurations mount the light fixture with a mounting bracket that allows for the removal and replacement of the light fixture in about the same time as a traditional light bulb change. Some configurations provide for fuse removal and replacement without the need to dismount the light fixture from its mounting bracket or without the need to open the housing of the light fixture to access the fuses. Some configurations use a battery backup system and self-check methods with LED light fixtures configured for public transportation applications.
