Abstract
Abstract The electric lock system combines an electric lock (2) with an energy control unit (13) such that when a guest key (12) is used in the lock, the lock communicates with the energy control unit to move from an unsold state to a sold state. Optionally, the guest key has information which tells the lock when the guest leaves and the lock communicates to the energy control unit to move from the sold state to an unsold state. Another option includes a motion detector (15) and door switch (14) which allows the lock to detect the presence of the guest in the room and allows the lock to further employ an occupied and unoccupied state. The combination of the electric lock system and the energy control unit provides energy savings in the heating and cooling of the room.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
207 words
An electronic lock system having an electronic lock mounted in a door of a room to provide access to said room; and a guest key card with a guest key code thereon for opening said lock, said lock having a means for storing a guest access code, a means for reading said guest key code when said guest key card is inserted into said lock and a means for comparing said guest key code with said guest access code such that if said guest key code matches said guest access code said lock opens, the improvement comprising: (a) an energy control means, said energy control means controlling temperature in said room, said energy control means having a means for communicating directly with said lock, and having at least two modes, a sold mode and an unsold mode, said unsold mode having a wider temperature range than said sold mode temperature range; and (b) said lock having a means for communicating directly with said energy control means such that said lock communicates with said energy control means when said guest key card has been used to open said lock such that said energy control means moves from said unsold mode to said sold mode at said start time.
Claim 2
Dependent Claim
20 words
The electronic lock system of claim 1 further comprising a means for detecting when a person is in said room.
Claim 3
Dependent Claim
61 words
The electronic lock system of claim 2 wherein said means for detecting comprises a detector mounted on a wall of said room and communicating directly with said energy control means; and a door switch mounted in said door jamb for detecting a change in state of said door, said door switch communicating said change of state to said energy control means.
Claim 4
Dependent Claim
47 words
The electronic lock system of claim 2 wherein said means for detecting comprises a detector mounted in said lock and a door switch mounted in said lock for detecting a change in state of said door, said detector and said door switch communicating directly to said lock.
Claim 5
Dependent Claim
44 words
The electronic lock system of claim 2 wherein said means for detecting comprises a detector mounted on a wall of said room and communicating directly to said energy control means; and a door switch mounted in said lock and communicating directly to said lock.
Claim 6
Dependent Claim
170 words
The electronic lock system of claim 1 wherein (a) said sold mode of said energy control means further comprises an occupied mode and an unoccupied mode; (b) a means for setting the temperature such that a person can set the temperature in the room to an occupied mode when said energy control means is in said sold mode; and (c) a detection means for detecting when a person is in said room, said means for detecting having a means for communicating with said energy control means such that, when said detection means detects a person in said room and said energy control means is in said sold mode, said detection means communicates with said energy control means and said energy control means operates in said occupied mode and when said detection means detects the absence of a person in said room and said energy control means is in said sold state, said detection means communicates with said energy control means and said energy control means operates in said unoccupied mode.
Claim 7
Dependent Claim
61 words
The electronic lock system of claim 6 wherein said means for detecting comprises a detector mounted on a wall of said room and communicating directly with said energy control means; and a door switch mounted in said door jamb for detecting a change in state of said door, said door switch communicating said change of state to said energy control means.
Claim 8
Dependent Claim
47 words
The electronic lock system of claim 6 wherein said means for detecting comprises a detector mounted in said lock and a door switch mounted in said lock for detecting a change in state of said door, said detector and said door switch communicating directly to said lock.
Claim 9
Dependent Claim
44 words
The electronic lock system of claim 6 wherein said means for detecting comprises a detector mounted on a wall of said room and communicating directly to said energy control means; and a door switch mounted in said lock and communicating directly to said lock.
Claim 10
Independent Claim
88 words
A method for controlling an energy control means used for controlling the temperature in a room, said method comprising: (a) inserting a guest key card in an electronic lock mounted in a door of a room such that said lock reads a guest key code off of said guest key card and opens said lock; (b) communicating to said energy control means that said lock has been opened by said guest key card; and (c) moving said energy control means from an unsold state to a sold state.
Claim 11
Dependent Claim
49 words
The method of claim 10 wherein said method further comprises the steps of: (a) detecting the presence or absence of a person in said room each time said door changes state; and (b) communicating to said energy control means the presence or absence of a person in said room.
