Abstract: A holster is provided with an improved attachment interface. The attachment interface is integrated as part of the holster housing and provides a railed track within a circular retaining wall. The attachment interface interchangeably accommodates a variety of different accessory attachments and mounting configurations.

Abstract: A mounting apparatus for a portable communication device is provided. The mounting apparatus is mountable and secured onto a wearable garment or other external substrate using both magnetic engagement and tethers. The mounting apparatus minimizes shaking of the portable communication device and/or the possibility of the portable communication device getting knocked off the external substrate.

Abstract: A portable communication device (200) provides a remote speaker microphone (RSM) (204) that is adaptable to a plurality of interchangeable bridge interface modules. The plurality of interchangeable bridge interface modules may comprise interchangeable camera (212), (218) and non-camera (220) bridge interface modules that couple between the RSM (204) and a power source (208). The power source (208) may also be interchangeable via a portable battery (212) or corded power module (214). The portable communication device is shoulder mountable and well suited to portable public safety applications.

Abstract: A removable cartridge for a portable communication device. The removable cartridge includes frame having a first surface, and an opposite second surface. The second surface is non-planar and is shaped to conform to a shape of a speaker cone in the portable communications device. The removable cartridge also includes a membrane coupled to the first surface of the frame. A portion of the membrane is suspended over an open gap defined by the frame.

Abstract: A shoulder mountable communication device provides a remote speaker microphone (RSM), a camera, and a battery. The device is conformable to different user's to provide for a maximum imaging field of view and hands-free operation of the camera.

Abstract: A process at an electronic digital assistant (EDA) computing device uses natural language detection of a user status change to make corresponding modification of a user interface associated with the user. The EDA monitors a private or talkgroup voice call associated with a user and detects first user speech from the user. The EDA identifies a current status of the user of on-assignment or not-on-assignment and determines that the first user speech is indicative of a first or second user status change. When it is the first user status change, the EDA causes a mobile or portable computing device associated with the user to automatically swap a foreground not-on-assignment related application with a not-previously-in-foreground on-assignment related application, and vice versa when it is the second user status change.

Abstract: A multi-position rotary control provides authentication for a battery operated portable communication device. The rotary control provides a rotary switch pin code which is combined with voice authentication as part of an authentication process. Upon completion of authentication, the rotary control reverts back to a default radio control.

Abstract: A shoulder harness for supporting an electronic device includes a substrate having a pre-formed curvature such that the shoulder harness is biased to an at-rest state that is concave on a bottom-facing surface. A crest portion includes at least one slit adapted to secure the shoulder harness to a fastening element on a garment or other body-worn device. A front portion is coupled to the crest portion and extends in a forward direction from the crest portion. The front portion includes a receiving opening for attachment of the electronic device. A rear portion is coupled to the crest portion and extends in a rearward direction from the crest portion.
