1 AMENDED CLAIMS received by the International Bureau on 31 July 2013 (31 .07.2013) 1. An electronic device with gesture activation comprising: a body including at least one infrared (IR) transmissive window; an IR gesture detection sensor located within the body and aligned with the transmissive window; a processor located within the body and coupled to the gesture detection sensor; and digital memory disposed within the body and coupled to the processor where the memory includes codes segments executable on the processor for; (a) starting a timer if a first gesture of an activation gesture sequence including an ordered plurality of gestures is detected by said IR gesture detection sensor while at least one process of the electronic device is in an inactive mode; and (b) activating the at least one process of the electronic device if the remainder of ordered plurality of gestures is received before the timer has elapsed. 2. An electronic device with gesture activation as recited in claim 1 wherein the electronic device is a portable digital device provided with a display screen. 3. An electronic device with gesture activation as recited in claim 2 wherein the portable digital device includes a wireless connection to a network. 4. An electronic device with gesture activation as recited in claim 3 wherein the network is at least one of a cellular telephone network and the Internet. 5. An electronic device with gesture activation as recited in claim 4 wherein the inactive mode is a sleep mode. 2 6. An electronic device with gesture activation as recited in claim 4 wherein the inactive mode is a locked mode. 7. An electronic device with gesture activation as recited in claim 1 wherein the inactive mode is one of a plurality of operational modes of the electronic device, 8. An electronic device with gesture activation as recited in claim 1 wherein the inactive mode is one of a plurality of operational modes of the electronic device, 9. An electronic device with gesture activation as recited in claim 1 wherein an activation gesture sequence Sunio^ is a tuple of arbitrary length n written as Su„|0Ck = O - g2» §3» Sn where the k,h gesture in the n-tuple is denoted by g^. 10. An electronic device with gesture activation as recited in claim 9 wherein the timer is set to a window length Tdetect such that the activation gesture sequence Su,,^* must occur within the window length Tdetect- 11. A method for activating an electronic device with gestures comprising: detecting hand gestures using a gesture detection sensor; starting a timer if a first gesture of an activation gesture sequence including an ordered plurality of gestures is detected by said gesture detection sensor while at least one process of an electronic device is in an inactive mode; and activating the at least one process of the electronic device if the remainder of an ordered plurality of gestures is received before the timer has elapsed. 12. A method for activating an electronic device with gestures as recited in claim 11 further comprising detecting gestures with an IR gesture detection sensor. 3 13. A method for activating an electronic device with gestures as recited in claim 12 wherein the electronic device is a portable digital device including a display screen and wireless connection to a network. 1 . A method for activating an electronic device with gestures as recited in claim 13 wherein the inactive mode is a locked mode. 15. A method for activating an electronic device with gestures as recited in claim 14 wherein the inactive mode is one of a plurality of operational modes of the electronic device. 16. A method for activating an electronic device with gestures as recited in claim 1 1 wherein the gestures include left swipe and right swipe. |
