Abstract: A scanning assembly is disclosed. The scanning assembly comprises a mobile electronic device comprising an optical sensor, the mobile electronic device adapted to perform a scanning operation, and a trigger assembly. The trigger assembly comprises a handle member adapted to be releasably coupled to the mobile electronic device, the handle member comprising a light source, and a switch assembly adapted to receive input from an operator of the trigger assembly, wherein the light source is adapted to emit a light signal in response to manipulation of the switch assembly, and wherein the mobile electronic device is adapted to perform the scanning operation in response to receiving the light signal with the optical sensor.

Abstract: A handle for a mobile device includes a housing coupled to the mobile device; a surface of the housing being contoured to substantially conform to a natural curvature of a hand of the user. The handle also includes a perch coupled to the housing and extending substantially perpendicular to a longitudinal axis of the housing.

Abstract: A data input arrangement for a mobile device which includes a first group of input keys, a second group of input keys and a break. The first group defines a first typing surface on the mobile device. The first typing surface defines a first shape. The second group defines a second typing surface on the mobile device. The second typing surface defines a second shape different from the first shape. The break is situated between the first and second groups to separate the first and second groups from one another.

Abstract: A data input arrangement may include a first array of input keys defining a first shape extending across a first typing surface thereof; and a second array of input keys defining a second shape extending across a second typing surface thereof. The first and second arrays are contiguous with one another so that the first and second shapes create a non-linear surface extending across the data input arrangement. The non-linear surface enables users to tactilely locate individual keys of the first and second arrays.

Abstract: A data input arrangement includes an array of input keys arranged on a surface; and a perch at least partially extending between first and second rows of the array substantially parallel to one of the first and second rows. The perch extends away from the surface above each of the input keys. The perch is non-responsive to contact and electrically decoupled from a device receiving input from the data input arrangement.

Abstract: A data input arrangement includes an array of input keys extending across a typing surface. At least one of the input keys includes a first viewable surface displaying a first set of input data and a second viewable surface angled relative to the first viewable surface. The second viewable surface displays a second set of input data.
