Method of maintaining the flow rate of a refrigerant while maintaining superheat
A method of maintaining a fluid flow rate in a heating, ventilating, air conditioning, and refrigeration (HVAC-R) system while maintaining superheat in the HVAC-R system at a desired level includes: continuously measuring an operating fluid temperature of the HVAC-R system and calculating superheat at a pre-determined rate, determining if the calculated superheat is stable, measuring and recording an operating fluid pressure of the system each time the calculated superheat is stable, recording an average operating fluid pressure each subsequent time the superheat is stable, calculating an output PWM and reducing fluid flow through a metering valve when an actual PWM is greater than the calculated output PWM by adjusting a PWM signal to a microvalve in the metering valve, and increasing fluid flow through the metering valve when the actual PWM is less than the calculated output PWM by adjusting the PWM signal to the microvalve.
TEMPERATURE CONTROL DEVICE
A temperature control device (2) comprises a number of active thermal sites (6) disposed at respective locations on a substrate (10), each comprising a heating element (13) for applying a variable amount of heat to a corresponding site of a medium and a thermal insulation layer (16) disposed between the heating element and the substrate. At least one passive thermal region (8) is disposed between the active thermal sites (6) on the substrate (10), each passive thermal region (8) comprising a thermal conduction layer (18) for conducting heat from a corresponding portion of the medium to the substrate (10). The thermal conduction layer (18) has a lower thermal resistance in a direction perpendicular to a plane of the substrate (10) than the thermal insulation layer (16). This enables precise control over both heating and cooling of individual sites in a flowing fluid, for example.
Technologies for allocating ephemeral data storage among managed nodes
Technologies for allocating ephemeral data storage among managed nodes include an orchestrator server to receive ephemeral data storage availability information from the managed nodes, receive a request from a first managed node of the managed nodes to allocate an amount of ephemeral data storage as the first managed node executes one or more workloads, determine, as a function of the ephemeral data storage availability information, an availability of the requested amount of ephemeral data storage, and allocate, in response to a determination that the requested amount of ephemeral data storage is available from one or more other managed nodes, the requested amount of ephemeral data storage to the first managed node as the first managed node executes the one or more workloads. Other embodiments are also described and claimed.
Compensating for thermal lag in temperature compensated crystal oscillators
A temperature compensated crystal oscillator (TCXO) includes a crystal oscillator and a temperature sensor to provide a sensed temperature. A delay circuit has a selectable delay to delay the frequency compensation based on the sensed temperature. The delay compensates for a difference between when the temperature sensor reflects a change in temperature and when a frequency of a signal supplied by the crystal oscillator is affected by the change in temperature. The delay may be static or dynamic with respect to the current temperature sensed by the temperature sensor.
Techniques to process packets in a dual-mode switching environment
Various embodiments are generally directed to an apparatus, method and other techniques to receive a packet via an optical fabric, the packet comprising a switch mode indicator, determine a switch mode for the packet based on the switch mode indicator, and process the packet in accordance with a first protocol or a second protocol based on the switch mode.
System for controlling an environment of a structure
A system for modifying controllable elements of a structure based on an array of conditions, particularly a distance of a user or operator from the structure, deviations from an expected travel path to the structure, activities conducted either along or while deviating from the expected travel path, traffic, a core body temperature of the user or operator, and other factors. The controllable structure elements can include, for example, heating and air conditioning (HVAC), alarm, lights, and appliances.
Device, system and method for detecting overlap of an ophthalmic device by an eyelid
Techniques and mechanisms for sensing an overlap of an ophthalmic device by an eyelid of a user while the ophthalmic device is disposed in or on an eye of the user. In an embodiment, a circuit, disposed in a sealed enclosure of the ophthalmic device, interacts via an electromagnetic field with a film of tear fluid that is formed on the ophthalmic device. Based on the electromagnetic interaction, an oscillation characteristic of the circuit is evaluated. The oscillation characteristic varies with a resistance that is due in part to an eyelid of the user overlapping at least some portion of the ophthalmic device. Based on the evaluated oscillation characteristic, an amount of the eyelid overlap is determined by circuitry of the ophthalmic device. In another embodiment, the amount of eyelid overlap is used to determine one or more characteristics of gazing by the user's eye.
Memory sharing for physical accelerator resources in a data center
Examples may include sleds for a rack in a data center including physical accelerator resources and memory for the accelerator resources. The memory can be shared between the accelerator resources. One or more memory controllers can be provided to couple the accelerator resources to the memory to provide memory access to all the accelerator resources. Each accelerator resource can include a memory controller to access a portion of the memory while the accelerator resources can be coupled via an out-of-band channel to provide memory access to the other portions of the memory.
BELT WITH HEATING SECTION AND TEMPERATURE MEASURING DEVICE, AND SEAT BELT SYSTEM
The invention describes a belt retractor (10) for a vehicle including a locking disk (22) on which a locking element (24) is supported. In an extended position, the locking element (24) engages in locking teeth (28) on a frame (12) of the belt retractor (10). In a retracted position, the locking element (24) releases the locking teeth (28). There is further provided a clutch disk (38) which is motion-coupled with the locking element (24) via a control geometry (40) and a control element (36). The control geometry (40) comprises a first retraction area as well as a second retraction area for receiving the control element (36) in an at least partially retracted position of the locking element (36) and a first extension area as well as a second extension area for receiving the control element (36) in the extended position of the locking element (24). The invention further presents a method for releasing a mis-synchronized locking position of a belt retractor (10).
