Abstract: A mattress has a cover sewn over a cushioned non-absorbent core and is suitable for use as a resting place or sleeping space. The core is made of a netted material having a plurality of tangled, partially bonded filaments. The cushions can have various densities separated by baffles inside the cover. The cover can have a built in or added back support system. The mattress is a self contained carry case and needs no additional carry bag. A detachable shoulder strap doubles to carry the mattress and as adjustable straps to adjust the back support system. The cushion is manufactured in various sizes for standard outdoor camping as well as sizes for standard indoor bedding.

Abstract: Systems and methods for providing dispatch call features are provided. The dispatch call features include the ability to maintain multiple simultaneous dispatch calls and the ability to manage multiple dispatch stations. The maintenance of multiple simultaneous dispatch calls feature allows a dispatch station to place a current dispatch call on-hold to either initiate a new dispatch call or to accept an incoming dispatch call. The management of multiple dispatch stations feature allows a number of dispatch stations to be associated with one or more dispatch station identifiers. When a dispatch call is made to one of the dispatch station identifiers, all associated dispatch stations are paged. The first dispatch station to respond to the page is connected to the incoming dispatch call.

Abstract: When an ad hoc group call is initiated, or at a subsequent time but before the group call is terminated, a call originator may set a parameter to establish a time limit. The time limit is invoked when the call originator drops from the group call. The time limit may be set to zero time indicating that all participants will be disconnected and the group call will be terminated immediately upon exit of the call originator. The time limit may also be set to a predetermined amount of time, which indicates that the group call may remain up until the predetermined amount of time expires. If no parameter to establish a time limit is selected, the group call may remain indefinitely even after the originator exits the group call.

Abstract: The auto-fastening skeg system comprises a skeg receiver and a skeg. The skeg has a male component that cooperates with a cavity of the skeg receiver. The cavity has front and rear ends, a spring disposed at said front end and at least one dowel disposed between the front and rear ends. The male component includes a front tip and at least one locking wedge, said locking wedge corresponds in number to the number of dowels. When the male component is set in the cavity and the locking wedge is aligned with the dowel of the receiver, the spring pushes the front tip of the male component against the rear wall of the cavity of the receiver and the locking wedge against the dowel providing a locking mechanism that holds the skeg to the receiver.

Abstract: A method and computer-readable medium for displaying group call status information and participant status information for a group call are provided. Users participating in a dispatch group session (call) are provided with details about the group itself (group status) and the users participating in the group (participant status). When changes are made to the group call, the group call status information and the participant status information may be updated and displayed in real time.

Abstract: A wireless device and method for providing location updates to a wireless network includes determining a current location of the wireless device, comparing the current location to a second location and transmitting a location update, including presence information, to the wireless network when the current location differs from the second location by at least a predetermined geographical distance. The predetermined geographical distance is determined in accordance with at least one of subscription information associated with the subscriber unit, including a subscription fee paid, an enabled service and a network state. The current location may be determined via GPS, wireless network based position determination or other method.

Abstract: A shoe securement apparatus for a shoe employing a lace having opposite ends to interconnect two sides of the shoe. The apparatus includes a fastener plug attached to each of the opposite ends of the lace, a guide formed on each side of the shoe for engaging and directing the lace and a channel formed on each side of the shoe for receiving one end of the lace and its fastener plug. The fastener plug is forcibly engageable with the channel to secure the lace in the channel with the fastener plug being formed of a soft, flexible material such as a polymer. In one embodiment of the invention, the guide in an inclined groove and in another embodiment of the invention the guide is a knob with a curved wall which engages the lace. In yet another embodiment of the invention the lace is formed of a soft, flexible material such as a polymer.

Abstract: A behind-the-ear assistive listening receiver having a housing containing an RF receiver. The housing includes a cavity in which two or more crystal carriers are removably insertable. Each of the crystal carriers contains an oscillation crystal tuned to a particular frequency corresponding to an RF frequency desired to be received by the user. A switch is provided for permitting the user to select one of the oscillation crystals to automatically tune for the RF receiver to the desired RF frequency. Each crystal carrier may contain visible indicia indicating the frequency to which it is tuned, and the carriers may be positioned in the housing so that the indicia are generally visible to others when the receiver is worn by the user. The assistive listening receiver may also include a conventional hearing aid microphone for converting ambient sounds into an electrical hearing aid signal. A mixer is provided within the housing for mixing the hearing aid signal with the RF signal to provide a mixed output signal.

Abstract: Laces are secured through a shoe by a plurality of guides and indentations along the ankle portion of the shoe to tighten and take up slack of a shoelace which includes mating material attached to the ends and which is secured to a shoe by mating surfaces formed of interlocking bristle-like material, such as a hook and loop arrangement.
