|20140103753||HVAC Actuator Noise Reducer - An actuator noise reducer reduces the noise output of an HVAC actuator. The noise reducer has a spring arm with a sliding bearing surface which is pressed against a side of the rotating motor shaft. The spring arm introduces a generally radial force on the motor shaft, taking up bearing play and gently pressing the motor shaft into its bearing. A cylindrical hoop mount of the noise reducer mates with and encircles a cylindrical portion of the electrical motor adjacent the shaft for mounting the actuator noise reducer on the motor by axial sliding.||04-17-2014|
|20120199776||Quick Disconnect Actuator Mounting - A mounting apparatus and method couple an actuator to a valve or damper. The mounting apparatus includes five primary parts: a base which attaches to the valve or damper, an actuator mount which attaches to the actuator, a rotational coupler, a handle and a bail. The base and the actuator mount encircle the rotational axis in a mating relationship. The bail slides into aligned holes on the base and the actuator mount to secure the two together, preferably with legs on opposite sides of the rotational axis.||08-09-2012|
|20110006887||Programmable Communicating Thermostat And System - A programmable thermostat has two way communication with a utility using a power carrier line signal across distributed low voltage power lines in a building downstream of an HVAC system transformer. The two way PLC communication includes transmission to the utility of response information regarding the response taken by the thermostat to a power “shed” command, and preferably also includes sensed temperature and/or temperature set point information. The HVAC system transformer includes an integral capacitive bypass path for PLC data transmission across the windings of the transformer. The thermostat positions its temperature sensor to avoid heat given off by the PLC receiver/transmitter and its electrical circuits as well as the thermostat microprocessor and the electrical power circuits therefore.||01-13-2011|
|20090271001||BACnet Protocol MS/TP Automatic MAC Addressing - A Building Automation System (BAS) includes at least one Direct Digital Control (DDC) controller operating as a BACnet MS/TP master considered to be an “Anchor”. The Anchor operates an algorithm or method which automatically assigns BACnet Protocol MS/TP Media Access Control (MAC) addresses to other BAS components (considered Nomads) being installed into the network. The Anchor gathers MAC addresses existing on the MS/TP network, and issues an available MAC Pool Announcement. Each Nomad randomly picks a temporary MAC address. When the Anchor verifies singular communication at the temporary MAC address, the Anchor assigns a permanent MAC address to the Nomad, which can later be locked into flash memory. Using the preferred algorithm and method, Nomad devices are automatically assigned unused MAC addresses to join the MS/TP network in a non-conflicting, orderly way, with all communications occurring within the confines of BACnet MS/TP Protocol.||10-29-2009|
