Abstract: An electric vehicle pedestrian warning system includes an encapsulating container disposed in a location of an electric vehicle (EV) that is exterior to a cabin of the EV. The warning system also includes a speaker affixed to an interior portion of the container, an amplifier coupled to the speaker, a computer processor communicatively coupled to the amplifier, and logic executable by the computer processor. The logic is configured to transmit a sound file to the speaker through the amplifier over a vehicle network upon activation of the EV. The sound file includes a pedestrian warning sound. A first portion of the pedestrian warning sound is output by the speaker and amplified using acoustical properties of the encapsulating container. The first portion of the pedestrian warning sound is amplified in a low frequency range capable of being cancelled by an active noise cancellation system that is located in the interior cabin.

Abstract: A coordinated system of printed circuit board (PCB) assemblies for displaying information, such as advertising and pricing information. Each individual PCB assembly may display a unit price, such as a price for particular type of gasoline or other product. Each complete PCB assembly may have a number of Light Emitting Diode (LED) modules. The LED modules may be interconnected with one or more plug-in back panel modules attached to a housing and to power and control buses. The module housing may be interconnected with a main power supply and a controller. The controller may be configured to remotely and automatically change the price for each PCB assembly within the coordinated system. Each LED module may include a dedicated processor and be configured to have male connectors to plug into corresponding female receptacles on the power and control buses facilitating ease of installation, and replacement or repair of individual LED modules.

Abstract: A reflex speaker which provides an acoustic signal generator for acoustic alarm signals is captured in a housing through which the acoustic signals project via ports at the exit end of the housing. The housing defines a compartment at the exit end with an opening which is covered so that the acoustic signals project out of the exit end around the compartment. The cover may be a transparent cover which provides a lens through which optical signals generated by optics in the compartment provided by either LEDs to provide an optical warning signal, or a video camera, such as a CCD, which responds to visual signals as from hazards at the rear of the vehicle.

One of the base-side connection terminal and the output device-side connection terminal is configured using plural plates disposed in approximately parallel on the installation surface, and the other is configured using a plate sandwiched by the plural plates.

Abstract: A door bell includes a case and a frame is located within the open space of the case. An electro-magnetic valve is connected to the frame and controls two hit pins and a circuit board is connected to the frame and electronically connected to the electro-magnetic valve. Two resilient members are mounted to the hit pins which hit a sound plate located beneath the hit pins to generate sound. The sound is amplified by two sound boxes. The circuit board transfers alternative current into direct current so that no hulky part projecting from the door bell.

Abstract: A doorbell chime (100) can comprise a chassis (101), a cover (104) having a mechanical-cover identifier (105, 106), a mechanical-cover identifier detector (103) (to detect when the cover is at least substantially disposed in the installed position), and a chime (102) mounted in the chassis. This chime is configured to operate in a first mode of operation (302) when the mechanical-cover identifier detector detects the cover and in a second mode of operation (303) (that is different than the first mode of operation) when the mechanical-cover identifier detector does not detect the cover.

Abstract: This invention relates to systems to regulate pace. More particularly, this invention relates to providing a user with a regulated pace through the use of an electronic pace regulating, timing, and coaching device. In accordance with the instant invention, a portable programmable electronic device is configured to provide an audible signal at a repeated frequency that is selectable by the user. The pace timer and coaching device provides the user with a set audible cue at a set frequency to be followed during an exercise session. The audible cues provide a single regulated pace to be followed by the user while performing repetitive actions, motions, or strokes such that a desired training or racing pace is adhered to. The device is configured to detachably couple to swim goggles, to a user, to sunglasses, to an arm band, to exercise equipment, or to other articles of clothing utilized while exercising.

Abstract: Some embodiments of the present invention enable a user to select from different appearances and sound types by providing different door chime assembly housing covers. The housing covers can be different in shape, size, appearance, and/or acoustic property, and preferably can be releasably mounted a housing base. A door chime assembler, manufacturer, or user can therefore select from different door chime assembly appearances and acoustic properties by selecting one of two or more different housing covers. The door chime assembly can employ a number of different features that change the sound quality of the door chime assembly, including a domed or tented housing cover shape, a housing cover having curved edges and corners, an open acoustic chamber unbroken by internal walls, and side wall housing apertures. Other significant advantages are provided by the use of a door chime assembly transformer that is mounted to the door chime assembly housing.
