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.

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

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: A system and method for spiral contact force sensors includes a force sensor including a substrate, a first contact having a first spiral pattern formed on the substrate, a second contact having a second spiral pattern formed on the substrate, the first and second spiral patterns being interleaved, and a force sensitive material disposed so as to provide a variable resistance between the first contact and the second contact based on a force applied to the force sensor, wherein a force-resistance relationship of the force sensor is continuous as a radius of a circular region where the force is applied to the force sensor varies.

Abstract: A mobile communication device comprising a rotary input device, wherein the rotary input device comprises an optical sensor configured to sense rotation of the rotary input device and a processor coupled to the rotary input device configured to process input from the rotary input device. The rotary input device can, in an embodiment provide rotation inputs and keypad inputs.

Abstract: The mobile phone and the accessory communicate over a first line. The mobile phone computes or determines a challenge communication, and transmits the challenge communication over the first line to the accessory. The accessory receives the challenge communication, and computes a response communication based on the challenge communication, a hash algorithm and an electronic key. The response communication is transmitted over the first line to the mobile phone. The accessory also enables the phone accessory for use with the mobile phone. The response communication is received by the mobile phone. The mobile phone computes or determines a validation result based on the challenge communication, a hash algorithm and an electronic key. The mobile phone compares the response communication with the validation result, and enables the phone accessory for use with the mobile phone based on the comparison of the response communication with the validation result.
