Abstract: An economical ground heat exchanger system uses water-filled membrane liners in cylindrical augured holes. A submersible pump in a drain reservoir is shared by multiple boreholes. Thermal connection with a building or industrial process occurs through a heat exchanger thermally coupled to the reservoir. The pump sends water tempered by the heat exchanger to the water-filled holes, where it exchanges heat with the ground before overflowing through gravity drain piping back to the reservoir for continued recirculation. Heat transfer with the ground occurs through thermal contact between the water, the membrane liners, and earth supporting the liners. Optional raised borehole support rims maintain an “above grade” water level and allow removed soil to be re-used as a berm or planter over manifold pipes that connect the system components, thus eliminating the cost of trenching for the manifold pipes.

Abstract: A residential bathtub or shower is combined with a catch drain or basin below and in proximity with the tub or shower in a unitary structure. Most components of a heat pump are located in the catch basin. A hot water tank is outside of the catch basin but located in the immediate vicinity such as at an end of the tub or above the tub or alongside of the tub. The hot tank includes a heat exchanger that is the heat pump condenser, bringing heat to the hot tank for warming household water. Hot water flows from the tank into the tub or shower for bathing and then drains into the catch basin where heat exchangers remove heat before draining or reuse in flushing a toilet.

Abstract: Techniques for artifact mitigation in an optical system are disclosed. Light associated with a world object is received at the optical system, which is characterized by a world side and a user side. Light associated with a virtual image is projected onto an eyepiece of the optical system, causing a portion of the light associated with the virtual image to propagate toward the user side and light associated with an artifact image to propagate toward the world side. A dimmer of the optical system positioned between the world side and the eyepiece is adjusted to reduce an intensity of the light associated with the artifact image impinging on the dimmer and an intensity of the light associated with the world object impinging on the dimmer.

Abstract: Examples of light projector systems and methods of use. A method can include providing an optical device having a first surface, a second surface normal to the first surface, and a third surface arranged at an angle to the second surface. The third surface can be reflective to light of a first state and transmissive to light of a second state. An input beam having the first state can be normally incident on the first surface. A transmissive diffractive optical element on the first surface can convert the input beam into at least a first diffracted beam directed toward the third surface, where it is reflected by the third surface in a direction substantially parallel to the first surface. The reflected first diffracted beam can be modulated with image information using a spatial light modulator to produce a modulated light beam having the second state.
