Abstract: A circuit includes a first transistor, a second transistor, a PWM circuit, a minimum off timer, and a trigger circuit. The first transistor has a first control terminal, and the second transistor has a second control terminal. The PWM circuit has a first output coupled to the first control terminal, a second output coupled to the second control terminal, a first input, and a second input. The minimum off timer has a timer output coupled to a first input the PWM circuit. The trigger circuit has a trigger signal output, a trigger signal input, and a trigger signal received output coupled to the PWM circuit. The trigger circuit includes a latch circuit. The latch circuit has a first latch input coupled to the trigger signal input, a second latch input coupled to the timer output, and a latch output coupled to the second input of the PWM circuit.

Abstract: Functionalized molecular layers comprising a backbone of polymerized amphiphiles for placement on a surface of a scaffold, such as a hydrogel. Methods of preparing such molecular layers and hydrogels comprising the same are also provided, as are methods of use thereof.

Abstract: Described herein are adhesives that exhibit good cohesive and tack properties. In certain aspects, the adhesives can be applied to substrates using a low- or medium-pressure delivery system. The adhesives can be readily applied to any substrate such as, for example, a floor, wall, ceiling, countertop, and the like. The adhesives are particularly effective in adhering heavy materials such as, for example ceramic tiles and wall panels to walls.

Abstract: The present disclosure is directed towards an apparatus for holding a suture. The apparatus may comprise a carrier including a base. The carrier may be configured to retain a cover over the base. The base may be configured to mount the carrier on a fixture and include a primary wrapping path disposed thereon, the wrapping path for wrapping at least a portion of a suture thread. The apparatus may include a plurality of suture retaining canopies located at an outer portion of the primary wrapping path and projecting from the base. The suture retaining canopies may be configured to facilitate retaining a suture thread within the primary suture path. The apparatus may also include a needle retainer disposed on the base. The needle retainer may include at least one slot configured to retain a needle.

Abstract: Coating and adhesive compositions are disclosed comprising between approximately 2% to approximately 10% of urea added to latex-based compositions to prevent deterioration of the working quality of the compositions after being subjected to freeze/thaw cycles. Best results are obtained by dissolving the urea in water prior to the addition of other components, although urea may be added at other points in the mixing process.
