Abstract: A skin grafting system includes a plurality of hollow microneedles actuatable between a retracted position and an extended position. The system further includes a rigid member coupled to plurality of hollow microneedles, and a latch assembly having at least one latch moveably coupled to the latch assembly. The at least one latch is configured to move during actuation of the plurality of hollow microneedles, and the at least one microneedles are in the extended position.

Abstract: A dental x-ray sensor holder includes at least two clamping faces wherein at least one of the faces includes at least one and preferably a plurality of resiliently deformable gripping protrusions. The clamping faces are positioned in a moveable, spaced opposing relation, such that the faces may be physically moved together to physically impinge the x-ray sensor therebetween.

Abstract: An active material and light emitting device comprises an ultrasonic atomizer assembly and a light emission device. The active material and light emitting device further includes a housing containing the atomizer assembly and the light emission device such that the atomizer assembly is disposed above the light emission device. The light emission device emits light that is transmitted through a medial portion of the housing.

Abstract: A trimmer assembly for cutting a sheet or sheets of material. The trimmer assembly includes a carriage assembly that is removably connected to a base. The carriage assembly comprises a carriage and a saddle, with a blade fitting within the carriage. The carriage assembly is slidably positioned on a rail, the rail being rotatable relative to the base. A cut-line indicator, such as a print guard, is positioned between the rail and the base, and has a cut-line indicator edge for defining a cutting path of the blade.

Abstract: A dusting device is disclosed. There is a telescoping handle, a shank mountable to the handle, and a supporting fork mounted to the shank for relative rotation with respect thereto. A cleaning sleeve is replaceably mountable on the fork for single use dusting purposes. The angle of the fork with respect to the telescoping handle can be releasably fixed by a catch mechanism. While the catch is sufficiently strong to resist angle adjustment during normal dusting, it permits the angle to be adjusted by firmly pressing the end of the fork (with or without the sleeve thereon) against a wall while holding the distal end of the telescoping handle. This converts the duster from a wall duster, to a duster capable of cleaning the tops of ceiling fan blades, without the need for a consumer to touch a portion of the device near the duster head. In another aspect the device has two such adjustable forks for holding two such sleeves which can be used simultaneously.
