Two way remote controller

Claim 1

A system for remotely controlling a component of a device having an engine, the system comprising: a mainset, mounted at any suitable location on the device; and a handset operable by a user; wherein said handset includes (a) handset code generating means for generating a security code and a command code for controlling the component; (b) handset transmission means, responsive to said handset code generating means, for transmitting said handset security code and command code to said mainset; (c) handset reception means for receiving a feedback code transmitted from said mainset, indicative of the condition of the component controlled in accordance with said command code; and (d) handset indicator means, responsive to said handset reception means and responsive to said transmitted feedback code for providing the user an indication correlatable with said feedback code;

Claim 2

A system for remotely controlling a component of a device having an engine, the system comprising: a mainset, mounted at any suitable location on the device; and a handset operable by a user; wherein said handset includes (a) handset code generating means for generating a security code and a command code for controlling the component; (b) handset transmission means, responsive to said handset code generating means, for transmitting said handset security code and command code to said mainset; (c) handset reception means for receiving a feedback code transmitted from said mainset, indicative of the condition of the component controlled in accordance with said command code; and (d) handset indicator means, responsive to said handset reception means and responsive to said transmitted feedback code for providing the user an indication correlatable with said feedback code;

Claim 7

A system according to claims 1, 2 or 3, wherein said mainset control means further comprises first timing means, responsive to said mainset verification means and said mainset reception means, for measuring the time interval between the reception by said mainset reception means of said transmitted handset security code and the reception by said mainset reception means of said transmitted command code, and disabling said verification means when said interval exceeds a first predetermined period.

Claim 10

A system according to claims 1, 2 or 3, wherein said security code is a multi-digit code.

Claim 11

A system according to claims 1, 2 or 3, wherein said mainset control means further comprises first timing means, responsive to said mainset verification means and said transmitted security code by said mainset reception means, for measuring the time interval between the reception by said mainset reception means of said transmitted security code and the reception by said mainset reception means of said transmitted command code, and disabling said verification means when said interval exceeds a first predetermined period, and wherein said security code is a multi-digit code.

Claim 12

A system according to clam 1, 2 or 3, wherein said mainset control means further comprises first timing means, responsive to said mainset verification means and said mainset reception means, for measuring the time interval between the reception by said mainset reception means of said transmitted handset security code and the reception by said mainset reception means of said transmitted command code, and disabling said verification means when said interval exceeds a first predetermined period; and wherein said handset further comprises (a) memory means, responsive to said handset code generating means, for selectively storing said handset security code and retrieving said memorized handset security code for subsequent transmission thereof by said handset transmission means; (b) second timing means, responsive to said handset reception means and responsive to the reception of said vehicle feedback code by said handset reception means, for measuring a second predetermined period; and (c) automatic shut off means, coupled to said handset transmission means and responsive to said second timing means when said second predetermined period has been measured, for retrieving said stored handset security code and for generating a command code for deactivating the vehicle component, for transmission of said stored handset security code and said command code by said handset transmission means.

Claim 13

A system according to clam 1, 2 or 3, wherein said mainset control means further comprises first timing means, responsive to said mainset verification means and said mainset reception means, for measuring the time interval between the reception by said mainset reception means of said transmitted handset security code and the reception by said mainset reception means of said transmitted command code, and disabling said verification means when said interval exceeds a first predetermined period; and wherein said handset further comprises (a) memory means, responsive to said handset code generating means, for selectively storing said handset security code and retrieving said memorized handset security code for subsequent transmission thereof by said handset transmission means; (b) second timing means, responsive to said handset reception means and responsive to the reception of said vehicle feedback code by said handset reception means, for measuring a second predetermined period; and (c) automatic shut off means, coupled to said handset transmission means and responsive to said second timing means when said second predetermined period has been measured, for retrieving said stored handset security code and for generating a command code for deactivating the vehicle component, for transmission of said stored handset security code and said command code by said handset transmission means.
