Devices, systems and methods for detecting and evaluating impact events

摘要

An impact detection device for detecting impacts to a body part of a user and various supporting systems are discussed. In an example, an impact detect device can include a circuit board, a component having a first section and a second section, a battery, and a molding for housing the circuit boat, the battery and the component. The circuit board can include impact detection circuitry including at least two sensors and a communication circuit. A zone of reduced rigidity can connect the first and second sections of the component, with the circuit board secured to the first section. The battery can be secured to the second section of the component allowing for flex relative to the circuit board. The molding can be shaped and dimensioned for mounting to a body part of the user.

1. An impact detection device for detecting impact to a body part of a user, the device comprising: a single circuit board including impact detection circuitry comprising: at least two sensors, the at least two sensors comprising a first accelerometer and at least one of a gyroscope and a second accelerometer; a processor to process input signals received from the at least two sensors; and a memory device coupled to the processor and including instructions that, when executed on the processor, cause the processor to perform operations comprising: detecting, based at least in part on analysis of a first input signal of the input signals, that the user is in a period of sustained movement in a known predetermined direction relative to the user: determining, in response to detecting the period of sustained movement, a heading of the user based at least in part on acceleration vectors derived from the input signals, wherein the heading of the user corresponds to the direction of sustained movement detected from analysis of the first input signal; and determining an orientation of the impact detection device relative to the body part of the user based on the heading and at least one of the acceleration vectors; a battery mounted adjacent to the single circuit board; and a housing for the single circuit board and the battery, wherein the housing is shaped and dimensioned for securing adjacent to a portion of the body part of the user.
