A thermostat, of the type that employs latching relays to connect thermostat power to the various wires of the thermostat run, has a re-pulse feature that supplies latching pulses at a given interval, e.g., three hours, to ensure that the relays are in their proper state agreeing with the thermostat mode and the room temperature relative to the setpoint(s). In the case that the room air temperature is changing in a manner contrary to the current heating or cooling mode, which may indicate the latching relay has been knocked or bumped and needs to have its proper state re-established, the thermostat microprocessor issues pulses to the latching relay(s) more frequently, e.g., each 30 minutes, and the re-pulses may have a longer pulse width, e.g., increased from 20 ms to 25 ms.

A system and related techniques generate an interrogation request from an initiator device, such as a client desktop machine or other machine, to a mobile or other media player, such as a digital camera, MP3 player, video camera or other device or hardware to enumerate the media content contained in that device, along with associated properties. The collection of binary objects which encode the content, such as digital photographs, encoded audio files, digitized video or other media, may include or have associated with them a set of corresponding object properties which help to define each object, such as by defining a pixel color depth, audio codec or other property or attribute. According to embodiments of the invention, the initiator may communicate with the responding device using a media-aware protocol supporting an aggregate object property request, such that the initiator may identify one or all of the set of properties paired with all of the objects to be returned along with an enumeration of those objects. The initiator may then present, for example, a list of song titles along with the corresponding artist, track length, codec, display skins or other attributes or properties to a user, for example to select, delete, copy or otherwise manipulate the underlying objects, which may in one regard be separately retrieved from their identifier and properties. Because properties may be retrieved in conjunction with, at the same time and using a unified retrieval scheme, the need to query each object identifier one by one for associated properties is removed. The throughput and responsiveness of object property retrieval is therefore significantly enhanced.
