Abstract: Devices are provided to automatically access blood from beneath or within skin. These devices include an injector configured to drive a needle into the skin and subsequently to retract the needle from the skin. These devices additionally include a seal to which suction is applied. To drive the needle into the skin, the needle is first driven through the seal, creating at least one hole in the seal. The suction applied to the seal acts to draw blood from the puncture formed in the skin by the needle, through the at least one hole in the seal, and to a sensor, blood storage element, or other payload. These devices can be wearable and configured to automatically access blood from skin, for example, to access blood from the skin at one or more points in time while a wearer of a device is sleeping.

Abstract: A method of tracking injections includes depressing a plunger of a medication injection device, and sending and receiving ultrasonic signals from a plunger head installed within a barrel of the medical injection device. The method also includes measuring a time of flight for the signals to travel through the medication, and determining a position of the plunger head based on the time of flight of the signals. Additionally, a plurality of data samples representative of the position of the plunger are logged, and a distance the plunger head travels is calculated. This is used to calculate the quantity of the medication dispensed based on the distance the plunger head travels. An external device is then used to back-interpolate a time corresponding to each data sample logged in order to determine the time the quantity of medication was dispensed.

Abstract: A medication injection device includes a barrel and a plunger disposed to dispense a fluid from the barrel. A dosage tracking system is coupled to output data indicative of the fluid dispensed. A controller is disposed within the medication injection device and coupled to receive the data from the dosage tracking system. The controller includes logic that when executed by the controller causes the controller to perform operations including determining, based on the data, whether an air shot event occurred while dispensing the fluid.

Abstract: Various apparatuses and methods for tracking the administration of medication by medication injection devices are provided. A plunger head for a medication injection device may include a first component that houses electronic components and a second component that couples to the first component to form the plunger head. When the plunger head is installed within a barrel of the medication injection device the second component may separate the first component from medication contained within the barrel.

Abstract: Systems and methods for generating an input to a computing device based, at least in part, on movement data generated by one or more ultrasonic transducers are described herein. An example system may include at least one ultrasonic transducer configured to be mounted to a body surface that is proximate to at least one subsurface tendon, and a controller operably coupled to the at least one ultrasonic transducer. When mounted to a body surface, the at least one ultrasonic transducer is configured to detect movement of the at least one subsurface tendon. The controller is configured to operate the at least one ultrasonic transducer to generate movement data based on detected movement of the at least one subsurface tendon, and generate an input to a computing device based, at least in part, on the generated movement data.

Abstract: Devices are provided to automatically inject drugs or other payloads into or beneath skin. These devices include an injector configured to drive a hollow needle into the skin and subsequently to deliver the payload through the hollow needle. Applied suction acts to draw blood from the puncture formed in the skin through the hollow needle, into the device, and to a sensor, blood storage element, or other payload. In some examples, the blood is drawn through the hollow needle when the hollow needle is penetrating the skin. In some examples, these devices are additionally configured to retract the hollow needle from the skin and/or to perform some other functions. These devices can be wearable and configured to automatically access blood or deliver a payload into skin, for example, to operate at one or more points in time while a wearer of a device is sleeping.

Abstract: Methods and systems relating to compensation for discrepancies in an image that may be captured with a moving camera or a moving head. The visual artifacts in the visual field may be reduced or eliminated by monitoring head and camera movements for a Heads Up Display (HUD) application, and feeding back the movement data to a compensation circuit to eliminate or reduce the visual artifacts such as judder effect, as the head and the camera move relative to the objects that the camera may be capturing. The duty cycle of one or more pixels and/or one or more groups of pixels of the display may be varied at different rates for different head and camera movement speeds. The faster the camera or head moves the shorter the duty cycle that may be applied to the display so that the image has low persistence.

Abstract: In certain embodiments, a head-mounted display may include one or more displays for displaying images. A left and right movable disk may be placed respectively between the left and right eyes of a user and the one or more displays. The user may wear the HMD, and may adjust the spacing between the left and right disks while viewing the computer-displayed image or images through holes in the plastic discs. For example, the HMD may display a stereo colored bulls eye pattern, of which the user can only see a portion because their vision is restricted to on-axis viewing by the discs. The computer may instruct the user to move the HMD disks until the user can only see the color in the center of the bulls eye. In certain embodiments, by performing the foregoing adjustment, the eye may be oriented on the proper optical axis to look through an optimal location of a lens.
