Abstract: A remote speaker microphone (RSM) unit enables a user to use either a headset or an in-ear speaker with the RSM unit. The RSM unit includes a first RSM connection for communicating and connectable with the first connection of the headset; and a second RSM connection for communicating and connectable with the second connection of the in-ear speaker. Connecting either the headset or the in-ear speaker to the RSM unit disables the speaker and microphone of the RSM unit. At least one of the first and second connections are wireless, e.g., Bluetooth or NFC, and at least one of the first and second RSM connections are wireless connections communicable with the first and second connections, respectively. In addition or the alternative, at least one of said first connection and said second connection are electrical plugs and at least one of said first and second RSM connections are corresponding electrical jacks.

Abstract: A dual radio PTT system includes two PTT buttons that are located on two separate elements, such as small boxes, that are connected by separate cables to the radio interface box. The PTT buttons, can, if desired, be physically placed (located) on the user's body at one or more locations different from the electrical interface box.

Abstract: A headset includes two earcups that overlie and seal around the wearer's ears. The headset includes a system for suspension of the earcups on a helmet, as well as a speaker enclosure that provides increased structural strength without taking up additional space on the board. The headset also includes a battery compartment that can accept either one of two different size batteries to power the electrical components of the headset.

Abstract: A hearing protection headset that can be worn by a user includes left and right earcups. The headset includes a radio communication system enabling at least one radio signal to be received and played through one or both of the earcups. Noise control circuitry in the headset is configurable by a user between at least three active modes of operation—the circuitry having a first active mode in which the headset provides automatic noise reduction, a second active mode in which the headset provides automatic noise cancellation, and a third active mode in which the headset provides both automatic noise reduction and automatic noise cancellation. A switch is manually operable by the user to configure the circuitry between the first active mode and the second active mode and the third active mode.

Abstract: The present invention relates to cutting tool insert for metal machining on which at least on the functioning parts of the surface thereof a thin, adherent, hard and wear resistant coating is applied. The coating comprises a metal oxide/oxide composite layer consisting of two components with a grain size of from about 1 to about 100 nm. The oxide layer is under a compressive stress.

Abstract: Non-slip, non-constrictive, self-adhesive ice bag device for use with confined patients that comprises a flexible, preferably water-impermeable outer cover with an open end that is sealable with a leak-proof closure means, said cover having a layer of adhesive to temporarily attach said cover, when it is filled with the cooling medium, or one or more cooling packs containing the cooling medium, to the inside or the outside of a patient-care fabric that is arranged to be in close contact with an injured area of the patient, such that said cooling medium is then in close contact with said injured area, without slippage, and without the need for a potentially constrictive strapping and/or wrapping means.

Abstract: This invention relates primarily to a therapeutic method comprising the use of a flexible outer cover that allows quick and easy alternating insertions of separate heat and cold packs, and is attached using an adhesive layer or safety pins to a garment at a location on the garment that is in close contact with an injured area of the body when the garment is worm, to provide alternating cold and hot or hot and cold therapeutic treatments and to a contrasting thermal device comprising a flexible outer cover for use in this method, and an article of manufacture comprising said flexible outer cover and other optional elements to form said contrasting thermal device.
