Abstract: A dashboard interface may be displayed on a lab instrument to provide aggregate status information from a plurality of other interfaces organized into a single interface. The aggregate status information may be viewed by a nearby user of the lab instrument, and selecting portions of the information via a touchscreen display will navigate directly to a subsequent interface that may be used to view additional information or make configuration changes relating to the selected information. The dashboard may be used as a screensaver on a lab instrument when the instrument is not in use, or may be navigated to by an active user of a lab instrument, or both.

Abstract: Aspects of the technology relate to a braking assembly for a lateral propulsion system of a high altitude platform (HAP) configured to operate in the stratosphere. Power is supplied to a propeller assembly as needed during lateral propulsion so that the HAP can move to a desired location or remain on station. When lateral propulsion is not needed, power is no longer supplied to the propeller assembly and it may slowly cease rotating. However, in certain situations, it may be necessary to cause the propeller assembly to stop rotating as soon as possible. This can include an unplanned descent. Rapid braking can avoid the propeller blades from entangling in the envelope, parachute or other parts of the HAP. A reusable brake is employed to prevent uncontrolled rotation of the propeller on descent, or otherwise to prevent the propeller from spinning freely when not being used to propel the HAP laterally.

Abstract: The technology relates to techniques for transient voltage protection for low voltage circuits. A transient voltage protection circuit can include an input, wherein a transient voltage event causes a transient voltage at the input; a transient voltage suppression (TVS) diode implemented downstream from the input, wherein the TVS diode is configured to absorb energy of the transient voltage event; and a metal-oxide-semiconductor field-effect transistor (MOSFET) implemented downstream from the TVS diode; wherein: a gate voltage applied to the MOSFET is based on a desired on-state resistance of the MOSFET in the absence of the transient voltage; energy of the transient voltage event that is not absorbed by the TVS diode and that is transmitted past the TVS diode enters a drain of the MOSFET; and the MOSFET is configured to clamp in a linear mode in response to the transient voltage event.

Abstract: A system for performing hybridization assays comprises a cartridge for housing a flow through device, where the cartridge includes a test fluid chamber for facilitating a substantially uniform flow of a test fluid mixture through the flow through device, and a fluidics station to deliver the test fluid mixture to the cartridge. The cartridge has a chip holder that holds the flow-through device, which has an array of microchannel passages. The chip holder has a support for placement of the flow though device, the test fluid chamber for directing a substantially uniform flow of a test fluid mixture through the array of microchannel passages of the flow through device, and a first port that receives the test fluid mixture. The cartridge has a sealing system for preventing the leakage of the test fluid around the flow through device. The test fluid chamber is defined in part by a spade-like surface having an inlet for the test fluid mixture.

Abstract: A system for performing hybridization assays is disclosed which has a cartridge for housing an array device. The cartridge may include a test fluid chamber for facilitating a substantially uniform flow of a test fluid mixture through the flow through device, and may include a fluidics station to deliver the test fluid mixture to the cartridge. The cartridge has a plurality of channels to receive fluids used in the performance of hybridization assays and to keep them separate, if desired.
