Abstract: Described herein are techniques of characterizing electrical characteristics of a battery cell. The techniques employ a battery monitor coupled to a battery to measure voltage of the battery cell when it is in a recovery state after application of a stimulus (e.g., discharging or charging the battery). The measured voltage of the battery cell in the recovery state is then used to generate a characterization of the battery cell. The characterization may be used, for example, to match the battery cell with one or more similar battery cells to be coupled in a battery pack. In another example, the characterization may be used to verify authenticity of the battery cell.

Abstract: An apparatus for fixing a wearable structure and/or a user-feedback element to a user is provided. The apparatus includes a wearable structure configured to be worn by a user, and a grounding assembly, coupled to the wearable structure. The grounding assembly includes: (i) an inflatable bladder, coupled to a first portion of the wearable structure, and (ii) a cord, coupled to a second portion of the wearable structure and the inflatable bladder. The inflatable bladder is configured to receive a fluid from a source. The cord is configured to tighten around a portion of the user's body according to and in proportion with the fluid pressure inside the inflatable bladder.

Abstract: A fuel system includes a fuel injector having a split check assembly with a control piece, an outlet piece, and a check sleeve. A trapped volume is formed between the control piece and the outlet piece within the check sleeve, to hydraulically couple the control piece to the outlet piece. A starting rate shape clearance fluidly connects the trapped volume to a fuel cavity and is formed between the check sleeve and one of the control piece or outlet piece received therein, and modulates a starting rate shape of fuel injection from the fuel injector. Related methodology is disclosed.

Abstract: A fuel injector nozzle assembly includes a two-piece outlet check having a timing control piece and a rate control piece. A nozzle passage is formed between a nozzle body and a two-piece outlet check, and a sac cavity is formed by the rate control piece and the nozzle body and fluidly connects a through-hole in the rate control piece to nozzle outlets. A starting-flow clearance is formed by the rate control piece and the timing control piece, and is opened by moving the timing control piece relative to the rate control piece. Moving the rate control piece relative to the nozzle body opens a main-flow seat. The nozzle assembly provides a slow starting injection rate shape in a common rail or similar fuel system and improved controllability over minimum delivery quantities.

Abstract: A combined umbrella and canopy (10) that provides the advantages of both of these devices for providing maximum shade. The umbrella portion (12) is substantially similar to a standard beach umbrella having a vertical pole (16) with spokes or ribs (22, 24, 26, 28) extending radially outwardly adjacent the top (20) for supporting a fabric cover (30). The fabric cover (30) defines a front (32) and back (34) and at least two sides of the umbrella. The back (34) of the umbrella includes an additional length of fabric (36) that extends horizontally rearwardly and then curves downwardly and terminates in two spaced apart ends (38, 40). Each end includes a pocket (42, 44) that can be filled with sand to weigh the same down to maintain the ends on the beach. The additional fabric (36) is essentially a canopy (14). The umbrella structure (12) provides better support for the forward end of the canopy and prevents the same from collapsing when the wind conditions change.

Abstract: A tent (10) comprised of two panels (12, 14) are joined at their tops (16) but which have free lower ends resting on the ground. The tent (10) is maintained in its vertical position by a pair of elongated rods (22, 24) on the inside of each side panel that are arranged in an X configuration. The ends of the rods are positioned in pockets (26, 28, 30, 32, 34) provided in the interior of the four corners of each side panel and are somewhat rigid but capable of flexing outwardly to provide structural support for the side panels. Adjustment straps (40, 42, 44) along the vertical edges of the side panels are used to adjust the tension on the rods. In a second embodiment (110) only one side panel (112) is provided and a vertical pole (160, 162) is used to support the top of the panel. The slide panel (112) is also provided with crossbars in an X configuration. The vertical angle of the vertical support pole (160, 162) can be changed to adjust the height of the lean-to.

The apparatus includes one or more pods coupled to a garment, each pod including: (i) an internal structure, and (ii) an airtight bladder surrounding the internal structure, where the bladder is pneumatically coupled to a pneumatic device that is configured to control a pressurized state of the bladder. Each pod is configured to: (i) have a first degree of flexibility when the bladder of the pod is in a first pressurized state; and (ii) have a second degree of flexibility, less than the first degree of flexibility, when the bladder of the pod is in a second pressurized state different from the first pressurized state. Each pod provides a haptic stimulation to a wearer of the garment when the corresponding bladder is in the second pressurized state.

Abstract: The disclosed computer-implemented method for determining a proximity status between electrodes may include detecting an amount of electrical charge an electrode among other electrodes that are communicatively coupled to an artificial reality device. The method may further include determining, based on the detected amount of electrical charge at the electrode, a mutual capacitance measurement that indicates an amount of mutual capacitance between the other electrodes. The method may also include determining, based on the mutual capacitance measurement, a relative proximity status between the electrodes, where the relative proximity status indicates a degree to which the electrodes are in proximity with each other. The method may further include providing the determined relative proximity status between the electrodes as an input to the artificial reality device. Various other methods, systems, and computer-readable media are also disclosed.
