  • Publication number: 20210270416
    Abstract: Kinematic mounts are used frequently to hold objects such as mirrors, lenses, and other optical equipment. To adjust kinematic mounts, adjustment mechanisms are often required. Adjustment mechanisms can be used to make fine adjustments in applications where precision is required (e.g., laser system prototyping). Kinematic mounts that include never-before implemented form factors and structural elements require new adjustment solutions, and those solutions are described in this application. Adjustment mechanisms described in this application include a main body, a control frame, and control screws to adjust the orientation of the control frame. The control frame is coupled with a kinematic mount's housing, which rotates about a center of curvature of a bottom surface of the housing.

  • Publication number: 20210250859
    Abstract: A system and method for reducing energy consumption in a wireless network. In one embodiment, a system includes a network coordinator configured to manage access to a wireless network. The network coordinator includes a controller. The controller is configured to define a channel hopping list that specifies on which channel a beacon signal is transmitted in each slot frame of the wireless network. The controller is also configured to set a number of time slots in each slot frame based on a length of the channel hopping list. The controller is further configured to transmit a first beacon signal in each slot frame on a channel specified by the channel hopping list. The number of slots in each slot frame causes the first beacon signal to be transmitted on a same channel in each slot frame.

  • Publication number: 20210247590
    Abstract: Kinematic mounts disclosed in this application are made from three main components: a housing, a footing, and a tightening mechanism. The tightening mechanism includes three parts: a top portion, a bottom portion, and a locking interface mechanism. When the top portion, which includes a hollow tip with interior threading, is screwed down onto the bottom portion, which includes a threaded tip, the locking interface component is pressed against at least one interior surface of the housing that causes the housing to be pressed against the footing. This action holds the housing in place relative to the footing while simultaneously preventing unwanted movement of the housing during tightening.

  • Publication number: 20210244203
    Abstract: Kinematic mounts are used frequently to hold objects such as mirrors, lenses, and other optical equipment. To adjust kinematic mounts, adjustment mechanisms are often required. Adjustment mechanisms can be used to make fine adjustments in applications where precision is required (e.g., laser system prototyping). Kinematic mounts that include never-before implemented form factors and structural elements require new adjustment solutions. This application describes systems that include both novel kinematic mounts as well as new adjustment mechanisms developed to reorient the new kinematic mounts. Adjustment mechanisms described in this application include a main body, a control frame, and control screws to adjust the orientation of the control frame. The control frame is coupled with a kinematic mount's housing, which rotates about a center of curvature of a bottom surface of the housing.

  • Patent number: 11089605
    Abstract: A system and method for optimizing power consumption of energy harvesting nodes in a wireless sensor network. In one embodiment, a system includes a network coordinator. The network coordinator includes a wireless transceiver and a controller. The wireless transceiver is configured to provide access to the wireless sensor network. The controller is configured to determine whether a wireless device that is wirelessly communicating with the network coordinator is powered via energy harvesting. The controller is also configured to schedule, based on a determination that the wireless device is powered via energy harvesting, the wireless device to communicate via the wireless sensor network using a priority timeslot of a superframe of the wireless sensor network. The priority timeslot is a timeslot occurring in an initial portion of the superframe.

  • Patent number: 11078502
    Abstract: A method and cell line for producing polyketides in yeast. The method applies, and the cell line includes, a yeast cell transformed with a polyketide synthase coding sequence. The polyketide synthase enzyme catalyzes synthesis of olivetol or methyl-olivetol, and may include Dictyostelium discoideum polyketide synthase (“DiPKS”). Wild type DiPKS produces methyl-olivetol only. DiPKS may be modified to produce olivetol only or a mixture of both olivetol and methyl-olivetol. The yeast cell may be modified to include a phosphopantethienyl transferase for increased activity of DiPKS. The yeast cell may be modified to mitigate mitochondrial acetaldehyde catabolism for increasing malonyl-CoA available for synthesizing olivetol or methyl-olivetol.

  • Patent number: 11074300
    Abstract: Techniques for visualizing dependencies in a data analytics system are described. In an embodiment, a visualization system may receive datasets and dataset dependency information for the datasets. The visualization system may receive a first type of analysis objects from a first analysis object system and dataset dependency information from an analysis object dependency service. The visualization system may receive a second type of analysis objects from a second analysis object system. The second type of analysis object may include a JSON representation of a set of operations that are applied during analysis such as a set of programming instructions. The visualization system may traverse and analyze the JSON representation to determine, for a given analysis object, one or more parent dependencies. The visualization system can then generate a graph of the datasets and analysis objects.

  • Publication number: 20210093196
    Abstract: The invention provides devices and methods for non-invasive monitoring and measuring of intraocular pressure (IOP) of a subject. Embodiments include a lens that is adapted to fit on the subject's eye, a microstructure disposed in or on the lens, the microstructure having at least one feature that exhibits a change in shape and/or geometry and/or position on the lens in response to a change in curvature of the lens. When the curvature of the lens changes in response to a change in IOP, a corresponding change in shape and/or geometry and/or position of the feature may be used to determine the change in IOP. The change in the feature is detectable in digital images of the lens taken with a mobile electronic device such as a smartphone.
