Abstract: A computer system displays a first object that includes at least a first portion of the first object and a second portion of the first object and detects a first gaze input that meets first criteria, wherein the first criteria require that the first gaze input is directed to the first portion of the first object in order for the first criteria to be met. In response, the computer system displays a first control element that corresponds to a first operation associated with the first object, wherein the first control element was not displayed prior to detecting that the first gaze input met the first criteria, and detects a first user input directed to the first control element. In response to detecting the first user input directed to the first control element, the computer system performs the first operation with respect to the first object.

Abstract: While displaying an application user interface, a device detects a first input to an input device of the one or more input devices, the input device provided on a housing of the device that includes the one or more display generation components. In response to detecting the first input, the device replaces display of at least a portion of the application user interface by displaying a home menu user interface via the one or more display generation components. While displaying the home menu user interface, the device detects a second input to the input device provided on the housing of the device; and in response to detecting the second input to the input device provided on the housing of the device: the device dismisses the home menu user interface.

Abstract: A wearable device, while a respective session is active in a respective application, detects a first signal indicating that the wearable device in no longer being worn. In response, the wearable device causes the respective session of the respective application to become inactive. While the respective application is inactive, the wearable device detects a second signal indicating that the wearable device is being put on, and in response to detecting the second signal, in accordance with a determination that respective criteria are met, the wearable device resumes the respective session of the respective application. Further, in accordance with a determination that respective criteria are not met, the wearable device forgoes resuming the respective session of the respective application, wherein the respective criteria include a criterion that is met when a current user of the wearable device is determined to be an authorized user of the wearable device.

Abstract: A computer system, in response to detecting a first input on a rotatable input mechanism, in accordance with a determination that the first input is a first type of input: changes an immersion level associated with display of an extended reality (XR) environment generated by the display generation component to a first immersion level in which display of the XR environment concurrently includes virtual content from an application and a passthrough portion of a physical environment of the computer system. In accordance with a determination that the first input is a second type of input: the computer system performs an operation different from changing the immersion level associated with display of the XR environment.

Abstract: A computer system displays a first and second user interface object in a three-dimensional environment. The first and second user interface objects have a first and second spatial relationship to a first and second anchor position corresponding to a location of a user's hand in a physical environment, respectively. While displaying the first and second user interface objects in the three-dimensional environment, the computer system detects movement of the user's hand in the physical environment, corresponding to a translational movement and a rotational movement of the user's hand relative to a viewpoint, and in response, translates the first and second user interface objects relative to the viewpoint in accordance with the translational movement of the user's hand, and rotates the first user interface object relative to the viewpoint in accordance with the rotational movement of the user's hand without rotating the second user interface object.

Abstract: In some embodiments, a computer system facilitates depth conflict mitigation for a virtual object that is in contact with one or more physical objects in a three-dimensional environment by changing visual properties of one or more portions of the virtual object. In some embodiments, a computer system facilitates depth conflict mitigation for a virtual object that is in contact with one or more physical objects in a three-dimensional environment by displaying the virtual object in a virtual environment within the three-dimensional environment. In some embodiments, a computer system facilitates depth conflict mitigation for a virtual object that is in contact with one or more physical objects in a three-dimensional environment by variably changing visual properties of one or more portions of the virtual object and/or by variably displaying the virtual object in a virtual environment based on one or more characteristics of the depth conflict.

Abstract: A thermal valve unit is provided for use with an oil filled screw compressor. The thermal valve unit can be affixed to an exterior pipe segment and can include a thermally responsive element in thermal communication with compressed air traversing through the pipe segment. The valve unit can include a movable valve member actuated by the thermally responsive element that opens and closes oil passages to selectively route oil either to a heat exchanger prior to being delivered to the oil filled compressor, or directly to the compressor without passing through the heat exchanger.

Abstract: A mirror includes a mirror body with a reflective coating on at least one mirror surface. The mirror body is formed of a plastic into which a filler is mixed. The mirror body is preferably formed by injection molding of a mixture of the plastic and the solid filler. The mirror is used in optical imaging applications such as an infrared optical system.

Abstract: A mirror having improved resistance to heat distortion and loss of dimensional stability when exposed to heat radiation . The mirror has a substrate of glass or plastic having front and back surfaces which can be of similar or different shape , and is coated with similar or dissimilar low-emissivity reflected layers on both surfaces. Radiation is reflected by the back surface (away from the mirror) thereby reducing amount of energy which is absorbed at the back surface of the mirror. This equalizes the temperature through the mirror and reduces thermally included warping of the mirror.

Abstract: Low-cost composite infrared windows that are transparent to long wave infrared radiation (8-12 microns) that provide sufficient strength and impact resistance for automotive-type environments, and the like. The windows may be used with night vision systems for automobiles, surveillance imaging systems, and other applications requiring low cost, long wave infrared windows. In one embodiment, the composite infrared window is a sandwich comprised of a polyethylene plastic film bonded with an acrylic adhesive to a relatively thin (0.015-0.040 inch) silicon substrate. The thin silicon substrate is mechanically stiff and low cost, and transmits in the 8-12 micron bandpass. The thin (0.001-0.007 inch) plastic film provides an exterior particle impact absorbing layer sufficient to enable the use of the window in automotive applications.

Abstract: Production of precision reflective mirror surfaces on low cost, lightweight molded plastic substrates (10). The process involves making a master pattern (12) having a precision machined contoured surface (13) corresponding to the precision mirror surface desired on the plastic substrate. A release layer (14) and a reflective layer (17) are applied to the master pattern and then transferred to the molded plastic substrate (10), with a curable replication layer (18) therebetween preferably comprising a filler-reinforced polymer composition which is compatible with the polymeric substrate and has a low coefficient of thermal expansion (CTE) which closely matches the CTE of the substrate. The replication layer (20) is cured to replicate the precision of the surface (13) of the master pattern (12), which can be reused to produce a multiplicity of high precision molded plastic mirrors (21).
