Abstract: An ear-wearable electronic device comprises a shell having a uniquely-shaped outer surface that corresponds uniquely to an ear geometry of a wearer of the device. The shell comprises a first contact surface. A battery housing comprises a first mounting interface and a battery compartment configured to receive a battery. The battery housing has a shape that conforms to that of the battery compartment. A faceplate comprises a second mounting interface configured to couple with the first mounting interface of the battery housing, and a second contact surface configured to matingly engage the first contact surface of the shell. A flexible printed circuit board assembly (PCBA) is supported by one or both of an exterior surface of the battery housing and the faceplate.

Abstract: A hearing instrument may comprise a housing that defines a cavity, wherein the housing includes an inner side that is formed to conform with user anatomy, an outer side that is externally visible when the hearing instrument is placed within an ear of a user. The hearing instrument may further comprise circuitry disposed inside the cavity, wherein the circuitry includes an antenna disposed adjacent an inner surface of the outer side of the housing. A battery door may be attached to the housing, wherein the battery door is positioned such that a battery can be inserted and removed via the battery door, wherein upon insertion of the battery into the hearing instrument, the battery is disposed behind the antenna relative to the outer side of the housing.

Abstract: An ear-wearable electronic device has a shell with an outer surface. A mounting void goes through the outer surface of the shell and exposes an internal volume of the shell. The mounting void is located at an ear-contacting region of the shell. The ear-wearable device includes a photoplethysmography sensor assembly having an optical transmission structure mounted in the mounting void and having a distal end exposed proximate the outer surface. The distal end of the optical transmission structure conforms to the outer surface of the shell at the ear-contacting region. The distal end is in contact with ear tissue of a user of the ear-wearable electronic device during use.

Abstract: Example control systems for automated power management of a motive machine. The features are described with reference to a hybrid powered sweeper-scrubber machine, but is not limited as such. The machine can include a main machine controller (MMC) operably coupled to an engine, and a power module operably coupled to the MMC by a controller area network (CAN) bus. A sub-system, including a sub-system having one or more electrical components such as motors, can be operably coupled to the power module by the CAN bus. To provide automated power control, the power module can monitor a load of the sub-system, and using the monitored load of the sub-system, the power module can communicate sub-system load information to the MMC. The MMC can automatically adjust an engine speed based on the monitored sub-system load information and the selected functional mode of the machine.

Abstract: A motive machine can be selectively operable in a plurality of functional modes. The motive machine can include a drive wheel, a steering assembly, and a controller. The drive wheel can be rotatably secured to a body of the motive machine. The steering assembly can be operable to steer the motive machine. The controller can be in communication with a steering sensor, a steering motor, and a limit sensor, where the controller can be configured to synchronize the steering motor to the steering sensor as a function of a limit signal.
