Abstract: A power rack attachment system and associated method are provided. An example of the power rack attachment system includes a hand crank and a gearbox coupled to the hand crank, the gearbox comprising a plurality of gears connected to a lead screw, wherein the plurality of gears causes the lead screw to rotate in a vertical translation based on a radial motion of the plurality of gears. The power rack attachment system includes a guide housing connected to the gearbox, the guide housing comprising the lead screw, a vertically translating nut, and a guide rod, wherein the lead screw is connected to the vertically translating nut, such that rotation of said lead screw leads to vertical translation of said vertically translating nut. The power rack attachment includes a j-cup connected to the vertically translating nut, wherein the vertical translation of the vertically translating nut causes vertical translation of said j-cup.

Abstract: A virtual thermostat system and method are provided. The method accepts commands via a virtual thermostat interface for establishing temperature set points for a plurality of zones. Energy consumption information is also accepted from a plurality of energy consumption units. Each unit consumes energy at an associated peak power to supply a controlled temperature medium to a corresponding zone. The method also accepts temperature measurements for each zone. Then, consumption commands are sent to each energy consumption unit in response to associated zone temperature set points, while insuring that a combined peak power of the energy consumption units is less than a maximum peak power threshold. In one aspect, the virtual thermostat accepts temperature measurements from a plurality of physical thermostats, each associated with an energy consumption unit. Then, consumption commands are relayed to the energy consumption units via associated physical thermostats.

Abstract: A system and method are provided for calculating power using a voltage waveform shape measurement from a contactless sensor. An electrically conductive medium carries alternating current (AC) electrical current, associated with an AC voltage, from a source node to a destination node. AC current is measured through the electrically conductive medium. Using a contactless sensor, an AC voltage waveform shape is measured. The power usage at the destination node is calculated in response to the AC current measurement, the measurement of the AC voltage waveform shape, and an AC voltage potential. For simplicity, the AC current and AC voltage waveform shape may both be measured at a first node located between the source node and the destination node. The AC voltage potential used in the power usage calculation may be an estimate, an actual measurement, or a value supplied by an external source (e.g., the power utility).

Abstract: A thermostat user interface (UI) is provided for presenting calculated set point ranges. The thermostat UI has a major thermostat scale for presenting a current temperature and an overall range of feasible temperatures. A set point indictor indicates a set point input (e.g., desired temperature) with respect to the major thermostat scale. A minor thermostat scale presents a set point range, where the set point range is a range of permitted temperature measurement variations from the set point input. The set point range brackets the set point indicator with a maximum temperature value representing a highest temperature in the set point range, and a minimum temperature value representing a lowest temperature in the set point range. If high and low temperature set point indictors are used, then there are first and second minor thermostat scales bracketing, respectively, the high and low temperature set point indicators.

Abstract: A multi-dimensional energy control system is provided with an energy management software application that organizes the consumption of energy by a device as an n-dimensional energy space, where n is an integer greater than 2, and each axis in the energy space represents an energy consumption characteristic. The energy management application generates instructions for a device in response to calculating a compromise operating point in the energy space. A user interface (UI) connected to the energy management application has a display to receive a graphical representation of the energy space and compromise operating point, and an input to receive user commands for moving the represented compromise operating point in the represented energy space. The energy management application calculates the compromise operating point in the energy space to match the displayed compromise operating point.

Abstract: A method and system for access-controlled customer data offloading uses a blind public utility-managed device. A customer-managed device encrypts collected customer data using per-type, per-period keys and transmits the encrypted customer data to the utility-managed device. The customer-managed device further encrypts the per-type, per-period keys using a master key and transmits the encrypted per-type, per-period keys to the utility-managed device. When the current period ends (e.g., each day at midnight), the customer-managed device generates new per-type, per-period keys and continues the above customer data offloading using the new per-type, per-period keys. As a result, the customer offloads storage of customer data to the public utility without relinquishing control over access to the customer data. Moreover, the fact that the customer data are encrypted by data type and period allows the customer to access and expose the customer data in highly granular fashion.
