A digital camera with a housing has a digital image device (ICD) that preferably has a special shape and a flat light sensing surface. A lens directs light to the light sensing surface and electronics are connected to the ICD for capturing image data. A memory stores the image data. An inclinometer in the housing detects an inclination angle of the housing and is used to correct for various distortions or otherwise modify the image data. The aspect ratio of the digital image can also be selected. The ICD is mounted on a yoke for pivoting about at least one axis passing through the ICD plane to correct focus by following the Scheimpflug Rule and/or by collecting focus and distance information for multiple points to create a focus point landscape used, for example, to tilt the ICD to the best focus solution for the image.

A knee pad construction includes a shaped cushion element with a concave interior with a recess having a flowable gel insert therein. The recess and insert are shaped to accommodate the left knee or the right knee of an individual.

A helmet has shell with a front opening covered by a faceguard of elongated wire segments. Loopstraps engage around wire segments at sides and a crown of the shell and fasteners connect the loopstraps to the shell. The fasteners each have a nut extending from an inside of the helmet shell out into a hole of the shell and an aperture of the loopstrap, and a stud removably connected to the nut by pushing and turning the stud by about a quarter turn to lock the stud to the nut. A tension spring between a head of the stud and the loopstrap urges the stud away from the nut when the stud is rotated to unlock the stud for facilitating a quick removal of the stud from the nut and a quick disconnection of the loopstrap and faceguard from the helmet shell.

A fluid-level sensing device that uses the interaction of a first magnet attached to the distal end of an external micro switch arm and a second magnet positioned within the distal end of a pivoting float body to close a circuit within the micro switch and create a shut-off signal to stop fluid production. A single housing holds the micro switch and float body, wherein magnetic forces acting through the housing wall between them and other magnet-positioning materials that separate the two magnets cause signal production. After float body deployment, manual reset of the float body is accomplished via its lever-like distal end. The main body of the micro switch, which it is snap-fit into a fixed position within the upper housing chamber for use, is entirely encapsulated in waterproof material to protect it from corrosion. Alternative ways for quick mounting of the housing to a fluid-collecting pan are contemplated.

The invention provides a method and apparatus for separating a stack of folded sheets by inserting a first, second, third and fourth count fingers into four successive openings in the stack, and separating the stack between the second and third count fingers. Where separation is carried out after a desired number of folded sheets have passed the third count finger, a completed pack having the desired number of sheets may be formed downstream from the third count finger. The count fingers may be operatively mounted in count finger cassettes.

A rifle recoil absorbing strap assembly for absorbing rifle recoil from a rifle, the strap assembly preventing the bruising of a shoulder when firing the rifle and without having to permanently mount the strap assembly on a target shooting bench, a table or a horizontal support member. The strap assembly includes an elongated, flexible, horizontal first strap member with adjustable and releasable fastener. The adjustable and releasable fastener is used for securing together a first end and a second end of the first strap member. Also, the strap assembly includes a flexible, vertical second strap member with a first end and an opposite second end. The first and second end of the second strap member are adapted for receipt around a front portion of the rifle and secured thereto for preventing upward movement of the rifle when firing. Further, the strap assembly includes a rifle butt cradle adapted for receiving and securing a rifle butt of the rifle therein. Whereby, when the strap assembly is secured to a rifle securing object and the rifle is held thereon, the strap assembly greatly reduces rifle recoil during the firing of the rifle.

A three dimensional (3D) radio frequency antenna is positioned on one side of a conveyor which has a movable part for moving items, each of which has a radio frequency transponder, into and out of the antenna such that the items when in the antenna are completely surrounded by the antenna. The 3D antenna includes a plurality of coils which provide a 3D reading field in which all transponders in the reading field may be interrogated and also includes noise compensation coils at opposite ends of the reading field to minimize electromagnetic radiation from the antenna and also minimize noise from external sources. The radio frequency transponder includes a housing, a substrate within the housing, an integrated circuit and a printed circuit board mounted on the substrate. A coil is mounted on the substrate such as to be spaced therefrom with the spacing of the coil from the substrate enabling the encapsulant to completely surround the coil.

A cleaning device for cleaning toilets, bathroom fixtures, and other surfaces. The device encloses a reservoir contained in a hollow handle for storing a cleaning solution, with a cap connected to one end of the handle and a base connected to the other end of the handle. A brush, sponge or other scrubber or cleaning surface is preferably attached to the base. A manually operated flow control mechanism opens a valve which seals at least one exit or dispensing orifice at or near the base of the reservoir, and thereby allows volume of cleaning solution to be dispensed at a reasonably fast, controlled rate of flow. In one embodiment, manually operated vacuum pressure release orifices are located at the opposite end of the reservoir from the exit orifice and are normally closed, but may be opened to minimize or eliminate any vacuum (subatmospheric pressure) in the reservoir, thereby aiding the flow of liquid from the reservoir through the exit orifice.
