  • Publication number: 20170314253
    Abstract: The invention is for a modular building unit (10, 200, 210) for use in constructing a building. The building unit (10, 200, 210) has a planar body (12) having two major side faces (12.1) and two ends (12.2) between each side face (12.1), and a connection interface (28, 30) provided at each of the ends, for connecting similar building units (10, 200, 210) with complemental connection interfaces. The body (12) comprises three walls (14, 16, 18) arranged side-to-side and transversely spaced from each other, the three walls (14, 16, 18) thus defining two planar spaces (20, 22) therebetween, and a plurality of reinforcing webs (24) in the first space, for providing structural support to the building unit (10, 200, 210). The second space (22) defines at least one hollow cavity for receiving a matched insulation insert (25) thereby to impart insulating properties to the building unit (10, 200, 210).

  • Publication number: 20170282328
    Abstract: A power tool that includes a tool body housing, a drive system, a tool head and a connection system. The drive system is housed in the tool body housing. The tool head, which is configured to perform work on a work piece, includes a tool head housing and an input member that is driven by the drive system when the tool head is coupled to the tool body housing. The tool head can be engaged to the tool body housing in at least two pre-defined and distinct orientations. The connection system secures the tool head to the tool body housing in each of the at least two pre-defined and distinct orientations.

  • Patent number: 9743224
    Abstract: Systems and methods for continuous measurement of an analyte in a host are provided. The system generally includes a continuous analyte sensor configured to continuously measure a concentration of analyte in a host and a sensor electronics module physically connected to the continuous analyte sensor during sensor use, wherein the sensor electronics module is further configured to directly wirelessly communicate sensor information to one or more display devices. Establishment of communication between devices can involve using a unique identifier associated with the sensor electronics module to authenticate communication. Times tracked at the sensor electronics module and the display module can be at different resolutions, and the different resolutions can be translated to facilitate communication. In addition, the frequency of establishing communication channels between the sensor electronics module and the display devices can vary depending upon whether reference calibration information is being updated.

  • Patent number: 9717390
    Abstract: A steam cleaning apparatus comprising: a main body having a boiler and a pump; a main power switch; a cleaning head coupled to a main body through a joint; a yoke in the main body or the cleaning head, the yoke having an arm contacting a position sensitive switch so that when the main body is in a non-use position, the position sensitive switch prevents the main switch from supplying power, and when the main body is in an in-use position, the position sensitive switch allows the main switch to provide power.

  • Patent number: 9671128
    Abstract: An air conditioner including a frame, a fan operable to generate an airflow that moves in an airflow direction, and a first heat exchanger including a first end adjacent the air inlet, a second end adjacent the air outlet, an air inlet face that extends between the first end and the second end, an air outlet face that extends between the first end and the second end and faces opposite the air inlet face, and a longitudinal axis that extends through the first end and the second end between the air inlet face and the air outlet face. The heat exchanger is configured to transfer heat between the airflow and a cooling medium. A first heat exchanger angle is defined between the longitudinal axis of the heat exchanger and the airflow direction, and the first heat exchanger angle can be between about 3 degrees and about 20 degrees.

  • Patent number: 9618300
    Abstract: A kit for fitting a handwheel to a focussing control of a rifle scope is used to enlarge a focussing ring of the control, without having to remove the focussing ring from the control. The handwheel is secured by a headed bolt to a projecting stub shaft. The handwheel has a side plate supporting an outer rim that has a plurality of peripheral indentations to assist turning of the handwheel. The side plate has a central hole and a hub that projects axially from the side plate and defines a bore for receiving the stub shaft. The outer diameter of the hub is received within an outer end portion of the focussing ring. The hub has at least one abutment that co-operates with the stub shaft to inhibit relative rotational movement. A cap bolt extends through the hole to engage the stub shaft and secure the handwheel to the control.
