Abstract: Disclosed herein are systems and methods including polarization sorting metasurface microlens array devices. In certain embodiments, a polarization imaging device is provided. The polarization imaging device includes: a source of image light; a metasurface lenslet array comprising a plurality of repeating metasurface lenslets, where the plurality of repeating metasurface lenslets comprise a plurality of first metasurface lenslets configured to diffract the image light into a first polarization light in a first direction and a second polarization light in a second direction; an image sensor positioned in the optical path of the first polarization light and the second polarization light, and where the image sensor includes a plurality of image sensing units including a first image sensing unit positioned to sense the first polarization light and a second image sensing unit positioned to sense the second polarization light.

Abstract: A method for loading a stack of individual paper units into a dispenser includes inwardly pushing on a pair of oppositely disposed end portions of respective lateral walls of the dispenser, thereby releasing a drawer of the dispenser for sliding movement of that drawer relative to a remainder of the dispenser. The drawer includes first and second, oppositely disposed sidewalls, a bottom wall, and an arcuate front wall that has a dispensing aperture. The bottom wall of the drawer extends between the first and second sidewalls of the drawer, and the sidewalls of the drawer define an open end of the drawer opposite the bottom wall and, jointly with the bottom wall and arcuate front wall, defines a storage volume of the drawer. The drawer is slid outwardly relative to a remainder of the dispenser to thereby expose the first and second sidewalls and bottom wall of the drawer.

Abstract: A method for loading a stack of interfolded paper units into a dispenser includes inserting a stack of interfolded paper units into an interior volume of the dispenser through a dispenser opening. The dispenser has a lid having a dispensing aperture, as well as a movable platen that has a paper-engaging surface, and which is urged upwardly toward the dispenser opening. A bottom wall of the dispenser is disposed opposite the dispenser opening, and a lock of the dispenser is selectively engageable with the platen. The stack is placed on the platen and a downward force is exerted on the top surface of the stack to thereby push the platen downward until the platen has been engaged by the lock and has reached a locked position in which the paper-engaging surface has an oblique orientation relative to the bottom wall of the dispenser.

Abstract: A dispenser for sheet products comprising a base, an outer shell mounted to the base, wherein the outer shell has a first portion configured to enclose a stack of sheet products to be dispensed and a second portion having a dispensing opening, the first and second portion being non-detachably and non-movably fixed relative to each other, a platen reciprocally moveable relative to the base and spring biased toward the dispensing opening, and first and second columns respectively extending from the base parallel to a movement direction of the platen on opposite sides of the platen, wherein the outer shell is detachable from the base for inserting a stack of paper products between the first and second columns onto the platen.

Abstract: Integrated nanospray ionization package, comprising a nanospray emitter, a push button carriage with button element projecting through a bore in said package, an integral high voltage contact pin, a bore in said package for reversible protrusion of the nanospray emitter, a push-and-retract spring mechanism in which the range of forward motion of the emitter is not dependent on range of travel of the said button, and then upon actuation of said button element and spring element for retraction of said nanospray emitter, said nanospray emitter is pushed forward to establish electrical contact, and upon release of said button retracts and breaks the electrical contact.

Abstract: A microphone is mounted to apparatus in order to receive sound from a sound source. The apparatus has a microphone clamp to secure different microphones to a variety of musical instruments and other sound sources and may be used to directly mount a microphone to a variety of clamping surfaces. The mounting apparatus incorporates a dual jaw design to allow for easy, fast, and secure mounting to the clamping surface. The apparatus supports a quick release mechanism for easy and fast engagement and disengagement of the dual jaws, consequently reducing time needed to securely clamp and remove the mounting apparatus with the clamping surface. The release mechanism may include a dowel release having a hole through which the jaw stud is situated. The hole has two curved surfaces so that one of jaws may be moved without turning the jaw stud when the dowel release is depressed.

Abstract: An earphone assembly for an in-ear listening device is disclosed. The earphone assembly has an inner housing comprising a nozzle, configured to receive a sleeve for placement into a user's ear, and a balanced armature motor assembly. The balanced armature motor assembly is mounted in the inner housing so as to form an acoustical seal between the inner housing and the balanced armature motor assembly. The earphone assembly also includes an outer housing configured to receive the inner housing. The inner housing can comprise a recess for receiving a paddle of the balanced armature motor assembly. Alternatively, the outer housing can be formed with a nozzle for receiving a sleeve for placement into a user's ear canal, and the inner housing can comprise a spout, which is received in a recess in the outer housing.
