Wearable Device with Automatic and Temporary Sensor-Activated Band Contraction
This invention is wearable computing device for measuring biometric parameters whose contraction (e.g. tightness or looseness) around a person's wrist and/or forearm is automatically and temporarily changed based on information from one or more motion, optical, and/or electromagnetic energy sensors.
1 . A wearable computing device for the wrist and/or forearm comprising:
a display;
a motion sensor; and
an attachment member which is configured to be fastened around a wrist and/or forearm, wherein the device has a first configuration in which the attachment member has a first degree of contraction in order to fit in a relatively loose manner around the wrist and/or forearm and a second configuration in which the attachment member has a second degree of contraction in order to fit in a relatively snug manner around the wrist and/or forearm, and wherein the device transitions from the first configuration to the second configuration based on information from the motion sensor.
2 . The device in claim 1 wherein the motion sensor is an accelerometer.
3 . The device in claim 1 wherein the motion sensor is a gyroscope.
4 . The device in claim 1 wherein the motion sensor is an inclinometer.
5 . The device in claim 1 wherein the attachment member contracts when exposed to electrical current.
6 . The device in claim 1 wherein the device further comprises an actuator which contracts the attachment member.
7 . A wearable computing device for the wrist and/or forearm comprising:
a display;
an optical sensor; and
an attachment member which is configured to be fastened around a wrist and/or forearm, wherein the device has a first configuration in which the attachment member has a first degree of contraction in order to fit in a relatively loose manner around the wrist and/or forearm and a second configuration in which the attachment member has a second degree of contraction in order to fit in a relatively snug manner around the wrist and/or forearm, and wherein the device transitions from the first configuration to the second configuration based on information from the optical sensor.
8 . The device in claim 7 wherein the optical sensor is a spectroscopic sensor and/or light-spectrum-analyzing sensor.
9 . The device in claim 7 wherein the optical sensor is an optoelectronic sensor.
10 . The device in claim 7 wherein the optical sensor is an infrared light sensor.
11 . The device in claim 7 wherein the attachment member contracts when exposed to electrical current.
12 . The device in claim 7 wherein the device further comprises an actuator which contracts the attachment member.
13 . A wearable computing device for the wrist and/or forearm comprising:
a display;
a compression sensor; and
an attachment member which is configured to be fastened around a wrist and/or forearm, wherein the device has a first configuration in which the attachment member has a first degree of contraction in order to fit in a relatively loose manner around the wrist and/or forearm and a second configuration in which the attachment member has a second degree of contraction in order to fit in a relatively snug manner around the wrist and/or forearm, and wherein the device transitions from the first configuration to the second configuration based on information from the compression sensor.
14 . The device in claim 13 wherein the compression sensor is a pressure sensor.
15 . The device in claim 13 wherein the compression sensor is a strain gauge.
16 . The device in claim 13 wherein the compression sensor is a piezoelectric sensor.
17 . The device in claim 13 wherein the attachment member contracts when exposed to electrical current.
18 . The device in claim 13 wherein the device further comprises an actuator which contracts the attachment member.
