Title: Moisture pump for enclosure
Inventor: KEOUGH MICHAEL
IPC: B01D53/26
Filed: 2016-06-09
Granted: 2020-03-10
Abstract: Systems including a moisture pump (20) for removing moisture from an inside environment (16) to an outside environment (14). The moisture pump includes a housing (25) defining a heating chamber and a condensation chamber. Maintained by the housing is a desiccant (26), a heater (27), and a heat sink (28) for selectively adsorbing water vapor in the heating chamber when the heater is off and desorbing water vapor into the heating chamber when the heater is on. A valve assembly (29) is also maintained by the housing transitionable between an adsorption position and desorption position. The adsorption position allows water vapor to be selectively transmitted into the heating chamber from the inside environment. The desorption position allows water vapor to be transmitted from the heating chamber into the condensation chamber for transmission into the outside environment, respectively. Insulation is optionally used around the heating chamber to increase desiccant desorption efficiency.

Abstract: Provided are an electrolysis apparatus and an electrolysis method capable, in an electrolytic process for generating hydrogen, of reliably eliminating the danger of trace amounts of gas gradually accumulating in an electrolytic solution circulation line and reaching the hydrogen explosion limit. The electrolysis apparatus 1 is characterized in that a gas phase region 21, in which hydrogen gas can exist in a gas phase, is provided with a positive electrode gas-feeding line 20, which is for feeding positive electrode gas to dilute the hydrogen gas concentration and which connects the gas phase region 21 with a positive electrode-side gas-liquid separation means. The electrolysis apparatus and electrolysis method dilute the hydrogen gas concentration in the gas phase region 21 with the positive electrode gas and reliably keep the hydrogen gas concentration below the lower explosion limit as a result of the positive electrode gas-feeding line 20 feeding at least a portion of the positive electrode gas to the gas phase region 21.

Abstract: A grinding tool comprises a base on which a plurality of grinding blades (8) is arranged. The grinding blades (8) each include a substrate (16) and abrasive (22) that is bonded to the substrate (16) by means of a binder (23). In order to increase the service life and the total amount of material that is removed, the grinding blades (8) are reinforced by a filler resin (25). Since the grinding blades (8) are reinforced, their cyclic deflection about a zero position caused by workpiece machining operations is reduced, thereby preventing excessive wear of the grinding blades (8).

Title: Supply voltage droop management circuits for reducing or avoiding supply voltage droops
Inventor: JAFFARI JAVID
IPC: G06F1/30
Filed: 2017-04-13
Granted: 2021-01-12
Abstract: Supply voltage droop management circuits for reducing or avoiding supply voltage droops are disclosed. A supply voltage droop management circuit includes interrupt circuit configured to receive event signals generated by a functional circuit. Event signals correspond to an operational event that occurs in the functional circuit and increases load current demand to a power supply powering the functional circuit, causing supply voltage droop. The interrupt circuit is configured to generate an interrupt signal in response to the received event signal. Memory includes an operational event-frequency table having entries with a target frequency corresponding to an operational event. Operating the functional circuit at target frequency reduces the load current demand on the power supply, and supply voltage droop. A clock control circuit is configured to receive interrupt signal, access memory to determine the target frequency, and generate clock frequency adjustment signal to cause clock generator to adjust to the target frequency.

Abstract: Angular position readings are obtained during rotation of an apparatus in a borehole, and angular rate readings are obtained over time of the rotation. The angular rate readings are adjusted based at least on the angular position readings. The angular position measurement does not require calibrated magnetometers or accelerometers to function. Additionally, a dynamic scale factor calculation for an angular rate gyroscope (ARG) allows the ARG to be used over a much wider operating range than without such a calculation. Finally, an integrated angular rate from the ARG calibrated for bias and scale factor fills in positional information between the magnetometers' zero crossings to deliver a high resolution hybrid angular position system capable of measuring precise angular position at high and irregular downhole rotation rates.
