Abstract: An image of a sample collection device is captured. The image of the sample collection device is analyzed to determine whether the sample collection device includes a sufficient amount of fluid sample. The image of the sample collection device is validated based on a result of the image analysis.

Abstract: Thermo-responsive hydrogel composite (TRHC) desiccants having high adsorption capacities, fast adsorption/desorption rates, and low regeneration temperatures (Treg) compared to traditional desiccants. TRHC desiccants may be synthesized by freeze drying. The porous structures resulting from freeze drying copolymers of thermo-responsive polymers and/or hygroscopic agents may be combined with hygroscopic inorganic salts, resulting in TRHC desiccants having superior performance properties.

Abstract: Disclosed herein are compositions and methods for biological upgrading of electrocatalysis-derived formate presents a promising approach to sequester CO2, valorize curtailed electrons, and establish a sustainable formate bioeconomy.

Abstract: A putter is described. The putter includes a composite putter head having a high moment of inertia. The putter also includes a putter head face connected to the composite putter head. The putter further includes a hosel for mounting to a putter shaft. The putter also includes a plurality of sole weights mounted in a sole of the composite putter head.

Abstract: A golf putter has a shaft of composite materials, a putter head having a stud for mounting to the shaft of composite materials, and a grip affixed to the shaft. The shaft is a hollow shaft and the surface is sanded and cleaned before a first layer of pre-preg material is rolled onto the shaft and secured with an adhesive layer. At least one additional layer of the pre-preg material is rolled onto the first layer of the pre-preg material and secured using adhesive. Additional layers of pre-preg material may be applied to the hollow shaft. Cellophane is wrapped on top of the at least one layer of the pre-preg material prior to heat curing of the hollow shaft. After heat curing, the cellophane is removed and the surface is sanded and decorated.

Abstract: An example system comprising a pressure sensor array, a proximity sensor comprising circuitry to sense an object approaching the pressure sensor array based on a change in a resonance frequency of the proximity sensor, and a controller to receive from the proximity sensor the sensed change in the resonance frequency and designate the pressure sensor array as active responsive to the sensed resonance frequency being below a threshold or inactive responsive to the sensed resonance frequency being above the threshold, wherein a data transmission rate of the active pressure sensor array is greater than a data transmission rate of the inactive pressure sensor array.

Abstract: A system includes a controller for a DC to AC inverter including a processor configured to execute instructions to perform operations including: generating a first pulse for a first phase of a center-aligned PWM signal to alternately activate a first phase switch of a first switch group of the inverter for a first duration and a first phase switch of a second switch group of the inverter for a second duration within a period of the PWM signal; and generating a second pulse for a second phase of the PWM signal to alternately activate a second phase switch of the first switch group of the inverter for a third duration and a second phase switch of the second switch group of the inverter for a fourth duration within the period of the PWM signal, wherein the second duration is different from the third duration during a stall condition.

Abstract: The present disclosure provides a method of manufacturing a filter, wherein the filter comprises a filter body formed of a porous filtration material and a plastic support structure, the method including performing a first additive manufacturing step to form an initial portion of the support structure; positioning filtration material above or on the initial portion; performing a second additive manufacturing step to form a secondary portion of the support structure such that the filtration material is between the initial and secondary portions. Additionally, the filter body can be enclosed by positioning a first portion of the filtration material to overlay a second portion of the filtration material; and connecting the first portion of the filtration material to the second portion of the filtration material to define a pocket within the filter body, the support structure configured to maintain spacing between the first and second portions of the filtration material.
