Abstract: An electronic device may be provided with a dielectric cover layer, a dielectric substrate, and a phased antenna array on the dielectric substrate for conveying millimeter wave signals through the dielectric cover layer. The array may include conductive traces mounted against the dielectric layer. The conductive traces may form patch elements or parasitic elements for the phased antenna array. The dielectric layer may have a dielectric constant and a thickness selected to form a quarter wave impedance transformer for the array at a wavelength of operation of the array. The substrate may include fences of conductive vias that laterally surround each of the antennas within the array. When configured in this way, signal attenuation, destructive interference, and surface wave generation associated with the presence of the dielectric layer over the phased antenna array may be minimized.

Abstract: This disclosure generally relates to building automation systems, and more particularly to device enrollment techniques in a Building Automation System (BAS). In one example, the Building Automation System includes a central controller and one or more remote sensors/devices. The central controller is initially placed into its enrollment mode. An installer may then walk around the building uttering a predetermined verbal word or phrase. When a sensor/device hears the predetermined verbal word or phrase, the corresponding sensor/device enters its enrollment mode, and then becomes enrolled with the central controller of the Building Automation System. In some cases, the Building Automation System may include a security system.

Abstract: An endoscope includes a rigid section having an opening situated between two ends. The endoscope also includes a handle for manipulation and at the first end. An image capturing device is near the second end and is configured to provide a first view when pointed in a first direction. The image capturing device is moved with respect to a longitudinal axis of the rigid section in response to a movement of an extension portion of a shaft located in the opening and operatively coupling the handle and a first base part resulting from the manipulation of the handle. A fixing member is rigidly coupled to the rigid section and pivotably coupled to the first base part at a second pivot portion of the first base part, and a second base part is pivotably connected to the fixing member at a pivot portion of the second base part.
