摘要:
Semiconductor processing tools in a semiconductor processing facility are coupled to communicate with a power management system. The power management system monitors the power consumption status of each of the semiconductor processing tools. Using the power consumption status of each of the semiconductor processing tools, the power management system stages the operation of the semiconductor processing tools so as to maintain the power consumption of the semiconductor processing facility below a predefined maximum power consumption. Limiting the power consumption to less than the predefined maximum power consumption reduces the per die processing costs without incurring the expense of building a new semiconductor processing facility or without modifying the semiconductor processing tools for larger batch sizes or for greater throughput.

A gas off security device for a gas range, which includes a cross bar sized to span a control width of the gas range, is connected to the gas range via a left mount and a right mount. Each of a plurality of knob locks are slidably mounted on the cross bar and are used to define a slot sized to receive a handle portion of one gas control knob. The knob locks can be adjusted for different gas ranges via set screws that allow the knob lock to be set at a selected location along the length of the cross bar. The gas control knob is blocked from being turned from an off position to an on position when the cross bar is mounted to the gas range and the handle portion of the control knob is received in the slot of one of the knob locks.

A method of early detection of scaling on internal surfaces of conduits of water processing equipment, is provided herein. The method includes: transmitting ultrasonic signals through the wall of the conduits; deriving data samples from received ultrasonic signals or reflections thereof; calculating a moving average of the scatter of the ultrasonic signals, over time, based on the data samples; applying a statistical operand to the moving average, to yield a statistical distribution metric; determining a dynamic window defined by: (i) an upper boundary being the moving average plus at least a fraction of the statistical distribution metric and (ii) a lower boundary being the moving average minus the at least a fraction of the statistical distribution metric; generating a trend line being a smooth fitting of the derived samples; and monitoring the trend line within the window to detect a crossover of the trend line at either of the boundaries.

A system for processing electronic transactions according to policies is disclosed. The system includes a user module configured to store computer-readable information related to a user, and a policy module configured to store a plurality of policies for electronic transactions. Each policy for an electronic transaction includes a permission to access a physical space or item by a user. The system also includes a processor configured to receive a request to complete an electronic transaction by the user, and configured to dynamically apply, upon receipt of the request by the processor, the plurality of policies to the user based on the request to complete the electronic transaction. Methods and machine-readable mediums are also disclosed.

A telematics method and system facilitates customizing a plurality of vehicle content files, parameters, and features based on edits and selections from a user interface. A telematics provider maintains a database comprising a table, or tables that associate(s) user identification information with a vehicle VIN and equipment/features/content installed in/on vehicle devices associated with the VIN. Database updates may occur automatically, or upon a user instruction, when a TCU wirelessly transmits current equipment, content, and feature configuration information to a TOC coupled with the database. The telematics provider's server may provide the interface that facilitates the user logging in and editing features, content, and operational and performance parameters currently configured/installed in/on the vehicle' equipment and devices. The telematics provider may forward the user input from the interface to another provider after it verifies user log in credentials before the other provider begins a download to vehicle devices associated with the VIN.
摘要:
Filtered storage containers for hazardous waste, such as radioactive waste, more particularly plutonium in the form of oxides and salts, are made of stainless steel and include lids which are retained by retaining rings that utilize bayonet or ratchet closures that cooperate with rims that are integral with cans to hold the lids in place. Sealing arrangements are provided that each include an O-ring of a circular cross section which seals radially between the lid and rim, as well as a seal of cruciform cross section, which seal provides compression sealing between the lid and an annular shelf within the rim upon locking the retaining ring to the rim with the bayonet or ratchet fitting.
摘要:
A craft ruler employs a laser module which is longitudinally positionable along the ruler. A laser emits a beam which defines a crafting guideline on an adjacent surface. The angular position of the laser guideline may also be adjusted relative to the straight edge on the ruler. In addition, more than one ruler may be ganged together to form orthogonal lines or a grid.
摘要:
A ruler for craft applications has an efficient construction which employs a pair of tearing edges to facilitate tearing and a pair of measurement scales. The tearing ruler may be angularly oriented to facilitate either tearing or measurement activities. The tearing edges are defined by various waveform patterns. The tearing edges may be interchangeable.

The present invention is a mechanically assisted scissors that enhances user comfort, ease of use, and safety. The scissors includes first and second scissor members that have first and second blades and first and second handles, respectively. The scissors has a biasing means enclosed within a chamber, and a locking mechanism.
摘要:
A three-phase spindle motor has three terminals each driven with pulse width modulated signals. Rotation of the motor is controlled by iteratively measuring an electrical period of the motor, determining a rotational position of the motor, and synchronizing the sinusoidal pulse width modulation of the spindle motor with the measured electrical period. The electrical period of the motor is measured by detecting zero crossings in the a back electromotive force induced at a first terminal of the motor and determining the time between successive zero crossings. The rotation position of the motor is determined based upon the last measured electrical period and a location of last detected zero crossing. The zero crossings are detected by selecting a time window during which the back electromotive force signal is sensed for zero crossings. The time window is selected as a function of the last measured electrical period and the rotational position of the motor.
