Abstract
Certain embodiments provide a head array system for a power wheelchair, including a head array body and one or more lateral arms. The head array body includes shafts. Each of the shafts includes lateral arm receiving sections. The one or more lateral arms are detachably coupled to one of the lateral arm receiving sections of one of the shafts.
Claims22
A head array system for a power wheelchair, comprising:
- a head array body comprising shafts, wherein each of the shafts comprises lateral arm receiving sections;
- at least one lateral arm detachably coupled to one of the lateral arm receiving sections of one of the shafts;
- and
- at least one of a switch and a sensor coupled to the head array body via the at least one lateral arm,
- wherein the head array body comprises a microprocessor and an enable/disable mechanism, wherein the enable/disable mechanism instructs the microprocessor to:
- generate command signals in response to received activation signals from the at least one of the switch and the sensor if the enable/disable mechanism is in a selected enable mode, and
- disregard received activation signals from the at least one of the switch and the sensor if the enable/disable mechanism is in a selected disable mode.
4 more elements
A head array system for a power wheelchair, comprising:
- a head array body;
- at least one of a sensor and a switch;
- and
- at least one lateral arm operable to couple the at least one of the sensor and the switch to the head array body, wherein the at least one lateral arm comprises:
- a hollow, curved lateral arm tube attached to the head array body,
- a curved telescoping extension attached to the at least one of the sensor and the switch, wherein the telescoping extension is slidable from a selectable non-extended position, where the telescoping extension is substantially housed within the lateral tube, to selectable extension positions at least partially outside of the lateral arm tube, and
- a first securing mechanism operable to lock the telescoping extension into at least one of the selectable non-extended position and the selectable extension positions.
4 more elements
A head array system for a power wheelchair, comprising:
- a head array body comprising a microprocessor configured to generate command signals in response to sensor activation signals;
- and
- a plurality of sensors in an occipital pad attached to the head array body, each of the plurality of sensors configured to transmit an activation signal to the microprocessor in response to sensor activation,
- wherein the microprocessor:
- generates a command signal if the microprocessor receives the activation signal from all of the plurality of sensors in the occipital pad, and
- disregards the activation signal if the microprocessor receives the activation signal from less than all of the plurality of sensors in the occipital pad.
