Abstract: A utility knife includes a handle having a body and a receiving aperture. The utility knife further includes a collet at least partially receivable in the receiving aperture, and a sleeve that is engageable with and that surrounds the collet. The collet is configured to alternately receive one of a portion of a blade of a first type in a first slot and a portion of a blade of a second type in a second slot. The collet and the sleeve are co-rotatable relative the handle to move the collet to a secured position in which one of the blade of the first type and the blade of the second type are secured to the collet.

Abstract: A method for configuring a system having a wearable optical unit is disclosed. The method includes powering on the system, and in response to the system being powered on, using one or more processors to control the system to: determine whether to cause the system to run a configuration workflow, and in response to determining to cause the system to run the configuration workflow, (a) control the system in connection with configuring an interpupillary distance (IPD) for a user of the system, (b) determine whether the IPD is configured for the user, and (c) in response to determining that the IPD is configured for the user, control the system in connection with configuring a focus of the optical unit.

Abstract: A method at an electronic device with a display includes: displaying a user interface having a first region and a second region; receiving, and displaying in the first region of the user interface, a live video stream of a physical environment captured by a remote video camera; displaying, in the second region, a timeline corresponding to a timespan for a first portion of a duration during which the live video stream may have been recorded; in response to receiving a user interaction to move the timespan to a second portion of the duration, transitioning the displayed timeline to a new timeline that corresponds to the timespan for the second portion, and while transitioning, displaying, in the first region, a subset of video frames representing the first and/or second portion of the duration.

Abstract: A sealable housing for an optical scanner includes at least one surface operable to float with respect to other housing surfaces. An O-ring can be situated about a perimeter of a lid an inserted into a container to define a sealed volume. The lid can serve to remove heat while one or more container surfaces are used to establish optical axis directions for one or more optical systems.

Abstract: A storage rail assembly and an end cap system for a storage rail assembly are provided. A storage rail assembly includes a first rail configured to be coupled to a wall. The first rail extends from a left end to a right end along a first longitudinal axis. The assembly further includes a first left end cap coupled to the left end of the rail, the left end cap including a concave pocket extending inwardly from a left face of the first left end cap and having a pocket contact surface; and a right end cap coupled to the right end of the rail, the right end cap including a projection extending outwardly from a right face of the right end cap, wherein the projection is configured to be received in a pocket of a second left end cap to form a horizontal rail assembly.

Abstract: A water heater auxiliary heating system includes a heat pump. It further includes a first tap to circulate water from a water tank to a heat exchanger within the heat pump. It further includes a second tap to circulate water back to the water tank. The heat pump is controlled by an energy management system to preferentially operate based at least in part on a status of a site energy system that the energy management system is configured to manage. The water tank stores excess energy that is generated locally at the site energy system.

Abstract: A hand tool including a shear assembly is provided. The hand tool includes a first handle, a second handle, a cutting blade, and a linkage. The first handle forms a channel extending along a reference axis corresponding to an extension of the first handle. The second handle includes a cutting member. The cutting blade forms a first opening and a second opening. The linkage is attached, via a first fastener, in pivotal arrangement to the first handle at the channel and to the cutting blade at the second opening. The cutting blade is attached, via a second fastener, in pivotal arrangement to the second handle at the first opening.

Abstract: A hand tool including a shear assembly is provided, including a first handle, a second handle including a cutting member, and a cutting blade. The cutting blade forms a first opening and a second opening. The first handle is attachable in a first operating mode to the cutting blade at the first opening via a first fastener. The first handle is attachable in a second operating mode to the cutting blade at the second opening via the first fastener. The cutting blade is attached in pivotal arrangement to the second handle via a second fastener.

Abstract: Particular embodiments described herein provide for an inflatable carrier for use on a vehicle. The inflatable carrier can include securing straps to secure the air filled carrier to the vehicle and transportable item securing straps to secure a transportable item to the air filled carrier. The air filled carrier can be inflatable and deflatable (i.e., the air filed carrier can be inflated and deflated). Also, the air filled carrier can include a tightening mechanism to tighten the securing straps and secure the air filled carrier to the vehicle and a transportable item securing mechanism that can be used to tighten the transportable item securing straps to secure the transportable item to the air filled carrier.

Abstract: The present invention is a compositional blend having a polyester, an acetaldehyde reduction compound and less than 50 ppm of an optical brightener. The blend has utility for food and beverage molded containers where improved clarity and flavor retention are important without producing a haze. The acetaldehyde reduction compound can be a low molecular weight partially aromatic polyamide, a low molecular weight aliphatic polyamides or polyesteramide. The optical brightener preferably is a bis(benzoxazolyl) stilbene. Articles, and especially beverage containers, produced from the blend have a yellowness, b*, less than about 2.5.

Abstract: A hanger element for an electroplating rack, specifically for suspending earrings for pierced ears for plating comprising a conductor part threaded at one end for attachment to the rack and provided at its other end with a collet for receiving the stem of an earring, a jacket of chemically inert plastic material within which the part is embedded except for the threaded end and the colleted end and a removable cap mounted on the colleted end with one end abutting the jacket and the other extending beyond the colleted end, said cap containing an axial hole for snugly receiving the colleted end and an axial passage extending beyond the end of the hole through the end of the cap for snugly receiving the stem of the earring for engagement within the collet.
