    Abstract: Embodiments relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and portable and wearable media devices. Media devices may include RF transceivers and proximity sensors for detecting a user, another wireless device, or both that are positioned in proximity of the media device and take one or more actions upon detecting proximity. Activity, content, data, playlist, media playback, command, control, data or file synchronization, and other functions may be handled by the media device subsequent to detecting proximity of another device and/or user in proximity of the media device. Moreover, those functions may be transferred back to the another device when the another device moves out of a proximity range of the media device. RF signatures, RF signal strength, RSSI, and proximity detection sensors may be used to detect proximity, location, and presence (e.g., of a user or other persons) relative to the media device.

    Abstract: An improved microchip spectrophotometer device (101) having a wavelength-sensitive light detector sensor (155) located on a microchip (241) that detects returning broadband light (128) that is narrow-spectrum wavelength filtered by gratings or filtered, such as through an optical collection window (141) on the sensor (155). Optionally, at least a portion of the returning broadband light was produced by one or more solid-state light sources (103, 103A, 103B) incorporated into the microchip device. Multispectral spectroscopic data from the detector is optionally transmitted such as by wire (161), then analyzed by a processor such as a difference unit (167), located on the same microchip or on a processing microchip. Systems incorporating the improved microchip spectrometer, and methods of use are also disclosed.
