Abstract: The present application relates to a battery-powered electronic device, such as an electronic hearing protector, with switchable electrical contacts. The device includes a housing enclosing the battery and an electronics assembly. The electronics assembly is powered by the battery, and the electronics assembly comprises a processor controlled by updatable software. The device further includes a first electrical contact that is a ground line; a second electrical contact that is a data programming line in a first state, and that is a charging voltage line in a second state; and a third electrical contact that is a clock line in a first state, and that is a charge enable line in the second state. The first, second and third electrical contacts are accessible from outside the housing. A switch enclosed by the housing changes the second electrical contact between the first state and the second state.

Abstract: A short-range communication system is presented that includes a system control unit and a personal protective equipment device. The system control unit includes a network creator configured to create a short-range network on a wireless frequency, an interference detector configured to detect a device on an interfering frequency, and a control unit frequency hopper configured to, based on the detected device, scan a frequency range for an open frequency and switch the system control network to the open frequency. The personal protective equipment device includes a network joiner configured to join the short-range network and a device frequency hopper configured to switch the personal protective equipment device to the open frequency.

Abstract: A hearing protection system is provided. The hearing protection system has a first active hearing protection system. The first active hearing protection system is level-dependent. The hearing protection system also has a second active hearing protection system. The second active hearing protection system is level-dependent. Each of the first and second active hearing protection systems are configured to operate in an independent mode and a dual-protection mode. A dual-protection mode level dependent function of the second active hearing protection system is different than an independent mode level dependent function.

Abstract: A battery-powered electronic device, such as an electronic hearing protector (100) includes a housing (113) enclosing the battery and an electronics assembly powered by the battery, the electronics assembly comprises a processor controlled by updatable software. The device further includes a first electrical contact (119a) that is a ground line; a second electrical contact (119b) that is a data programming line in a first state, and that is a charging voltage line in a second state; and a third electrical contact (119c) that is a clock line in a first state, and that is a charge enable line in the second state. The first, second and third electrical contacts (119a-c) are accessible from outside the housing (113). A switch enclosed by the housing (113) changes the second electrical contact (119b) between the first state and the second state.
