Abstract: A protective case for an electronic device and an associated electrical peripheral device includes a structural member for receiving at least a portion of the electronic device and protecting the electronic device when the electronic device is installed in the protective case, an aperture that provides access to a user interface of the installed electronic device, a docking receptacle for removably retaining the electrical peripheral device, and a flexible member attached to the structural member and positioned in proximity to the docking receptacle. The docking receptacle includes a cavity for receiving at least a portion of the electrical peripheral device and an engagement mechanism for removably retaining the electrical peripheral device in the cavity. The flexible member is configured to temporarily deform toward the cavity of the docking receptacle in response to an external force applied to the flexible member.

Abstract: Sensor and/or power-harvesting apparatus are provided for sensing and/or harvesting energy across a relatively wide dynamic range of a driving rotational input. The apparatus may include a rotor magnet (10, 62) responsive to a driving rotational input (14, 64). Utilization of a togging effect or a magnetic spring effect results in certain rapid-rotation events where the rotor magnet can rapidly rotate regardless of a low rate of rotation of the driving rotational input. A coil assembly (28, 75) is magnetically coupled to the rotor magnet to generate a signal in response to rotation of the rotor magnet during the rapid-rotation events. This signal may be used to harvest electrical energy and/or may be processed to determine characteristics of the driving rotational input.

Abstract: A protective case for an electronic device and associated wireless electrical peripheral device includes a protective shell for protecting the electronic device when the electronic device is inserted in the protective shell, a docking receptacle including a cavity for receiving at least a portion of the associated electrical peripheral device and an engagement mechanism for removably retaining the received portion of the associated electrical peripheral device in the cavity; and a battery for charging at least one of the inserted electronic device and the retained wireless electrical peripheral device.

Abstract: A protective case for a portable electronic device includes a shell, an aperture, an internal electrical connector, a rechargeable battery, docking receptacles, and an external electrical connector. The shell receives at least a portion of the portable electronic device while the aperture provides access to a user interface of the installed portable electronic device. The internal electrical connector electrically interfaces with the installed portable electronic device. The docking receptacles provide docking locations for removably stowing wireless earbuds when the earbuds are not in use. Each docking receptacle includes an electrical interface for electrically interfacing the rechargeable battery of the protective case to the wireless earbuds for recharging. The external electrical connector receives electrical power from an external power source for recharging the rechargeable battery of the protective case.

Abstract: A slip form paving machine including a main frame supported by a front driven steering wheel and a pair of rear wheels that straddle the fore-and-aft center line of the main frame. An open top hopper is mounted on the frame and the lower end of the hopper communicates with an open bottom slip form, so that paving material, such as concrete fed into the hopper, will flow downwardly and be discharged from the slip form as the machine moves over the terrain. An outrigger frame is pivoted to the main frame about a horizontal axis and is located laterally of the rear wheels. The outrigger frame carries an outrigger wheel which is located laterally outwardly of the slip form and an inclined scraper blade is mounted forwardly of the outrigger wheel. When using a relatively wide slip form, the outrigger wheel is engaged with the terrain, and the rear wheel closest to the outrigger wheel is raised above the terrain so that the machine is supported on the outrigger wheel and the other of the rear wheels.

Abstract: A kit for converting a wheel chair into a walker for a patient comprising a seat for replacing the wheel chair bottom, a base for mounting the seat to the wheel chair to define an open space for the patient in front of the seat between the sides of the wheel chair, the seat positioned immediately below the patient's buttocks when the patient is standing in the space. The kit also includes an inverted U-shaped support bar is mounted across the front of the wheel chair in position where it can be grasped by the patient, the support bar retaining the patient between the sides of the wheel chair and the seat.

Abstract: The invention is concerned with a peristaltic action pump useful for douche and enema purposes and capable of delivering a uniform flow of liquid. The pump comprises a flexible tube affixed in a hemicircular shape and having a fluid input port at one end thereof and a fluid exit port at the other end thereof. A rotatable member is provided adjacent to and generally parallel to the plane of the hemicircle, the rotatable member being rotatable about an axis in line with the axis of the hemicircle. Means are also provided, coupled with the rotatable member for rotatingly driving it. A pair of levers are provided pivotally mounted intermediate thereof to the rotatable member, each at an equal and non-zero distance from the rotational axis of the member, a line from the mounting of one of the pair of levers to the mounting of the other of the pair of levers passing through the rotational axis of the member.
