Abstract: Methods, systems, computer-readable media, and apparatuses for determining a sedentary state of a user are disclosed. The apparatuses can be fastened to the user and include sensors configured to detect movement of the user. The apparatuses can also include a circuit coupled to the sensors. The circuits may be configured to determine, using the sensors, whether the user is sedentary; and in response to determining that the user is sedentary, determine one or more physiological attributes of the user of the device.

Abstract: Disclosed are systems, devices, and methods for connecting a flexible circuit to a battery. Conductive pads are formed simultaneous with mounting and reflowing circuitry components on a flexible circuit, where the conductive pads serve as preformed tabs capable of being joined to terminals of a battery. The flexible circuit can be bent in a manner so that the conductive pads are positioned adjacent to the positive and negative terminals of a battery, such as a coin cell battery. The conductive pads can be attached to the terminals to form a cost-efficient and space-efficient design connecting the battery to the flexible circuit.

Abstract: Disclosed are electronic devices for detecting contact or close proximity to an object to be detected. An electronic device includes a capacitive sensor enclosed by a housing and a controller coupled to the capacitive sensor, where the controller is configured to detect contact or close proximity to an object to be detected, and where the capacitive sensor includes a capacitor with a sensor electrode. The sensor electrode is separated from an outer surface of the housing by the housing. At least a portion of the housing includes a partially conductive material and the sensor electrode is in conductive contact with the partially conductive material, or the sensor electrode is in conductive contact with an electrically conductive element on an inner surface of the housing or at least partially embedded in the housing.

Abstract: Disclosed are devices and methods for detecting activation of an electronic device, including a biomedical and biometric device. The electronic device can operate in a low-power mode until it is determined that the electronic device is in close proximity to or in contact with a body, and activated. The electronic device can include a first sensor including a first capacitance sensor, a second sensor, and a controller coupled to the first sensor and the second sensor. The controller can receive a first signal from the first sensor and determine that the electronic device is in close proximity to or in contact with a body based on the first signal, and receive a second signal from the second sensor and determine that the electronic device is activated based on one or both of the first signal and the second signal. The electronic device can transition from the low-power mode to an active mode in response to determining that the electronic device is activated.

Abstract: Techniques provided herein are directed toward accurately determining when an item is removed from a blister pack by utilizing capacitive sensors. The capacitive sensors may be positioned on each blister of the blister and may detect the presence of the skin of the finger and/or the whether the blister has been deformed, which can occur when an item is removed from the blister. Some embodiments may determine whether skin was detected at the time of extraction to determine whether extraction was intentional.

Abstract: A method by a wireless communication device is described. The method includes transmitting a first sequence of high-power advertising packets. The method also includes transmitting a second sequence of low-power advertising packets at a same advertising rate as the high-power advertising packets. The high-power advertising packets and the low-power advertising packets include the same advertising information. The first sequence and the second sequence repeat in one or more cycles.

Abstract: A method by a wireless communication device is described. The method includes determining whether the wireless communication device is moving. The method also includes setting a low advertising rate for transmitting advertising packets in response to determining that the wireless communication device is moving. The method further includes transmitting one or more advertising packets at the low advertising rate.

Abstract: Disclosed are hypodermic needle devices with a dose dispensing mechanism and methods of using those hypodermic needle devices. The dose dispensing mechanism, which may be an electronically-controlled pump, may be used to measure out a specific dosage amount of a drug while compensating for environmental factors, such as temperature and pressure. This allows the device to be used by patients for self-administration since a specific dosage amount of the drug may be precisely delivered regardless of the environmental conditions at the time of delivery. The specific dosage amount may be set using the device or remotely, and a fingerprint sensor may be used to prevent injecting the drug into the wrong patient.

Abstract: Methods, systems, computer-readable media, and apparatuses for facilitating administering of medicine are disclosed.

Abstract: Techniques are disclosed for providing a flowmeter in a hypodermic needle device to measure the flow of a drug from a reservoir located within a hypodermic needle device through a needle assembly. In some embodiments a valve may be additionally provided to control the flow of the drug from a reservoir located within a hypodermic needle device through a needle assembly. Such functionality can help ensure the proper dosage is dispensed and/or determine when the drug is improperly dispensed.

Abstract: Disclosed herein are techniques for drug delivery measurement. A medicine delivery device includes a cartridge for storing a medicine, a needle assembly coupled to a bottom of the cartridge, a piston located in the cartridge for pushing the medicine to dispense the medicine from the cartridge through the needle assembly, and a sensor configured to measure a distance between the piston and the bottom of the cartridge. The sensor includes a triangulation-based distance measurement unit, a resonant frequency-based distance measurement unit, a time-of-flight-based distance measurement unit, or a frequency-modulated continuous-wave time-of-flight-based distance measurement unit.
