Medications or anesthesia cart or cabinet with facial recognition and thermal imaging
A cabinet or cart has at least one limited-access drawer or compartment and employs facial recognition (FR) to permit an authorized user to access the limited-access drawer or compartment. A visible light image of the user and a thermal image of the user are taken simultaneously or nearly simultaneously, with the thermal image serving to confirm the validity of the FR and authenticate the user's identity.
1. A medications or anesthesia cart or cabinet comprising:
a cabinet;
a computer control arrangement mounted on or in said cabinet and including a computer processor;
at least one locking compartment in said cabinet including an electro-mechanical lock coupled to said computer processor;
a first camera on said cabinet oriented to obtain an image of a user of said cart and adapted for providing a visible light image of said user to said computer processor;
a second camera on said cabinet oriented to obtain a thermal image of said user of said cabinet and adapted for providing said thermal image to said computer processor;
sensor means on or in said cabinet and coupled to said computer control arrangement to receive a user command to commence opening said at least one locking compartment;
said computer processor being further operative in response to the user command from said sensor first to compare data in said visible image with stored facial recognition data for at least one authorized user, and then if the visual image matches the stored facial recognition data for the at least one authorized user, determining whether data in said thermal image is sufficient to ensure that the thermal image is consistent with an image of a human face, and permitting said electromagnetic lock to unlock said at least one locking compartment when the visible image corresponds to the face of a given one of said at least one authorized user and said thermal image is consistent with the image of a human face, but operative to block the at least one locking compartment from opening when the visible image does not correspond with stored data that represents the face of said at least one authorized user or when the thermal image is not consistent with the image of a human face.
2. The medications or anesthesia cart according to claim 1 ,
wherein said computer processor includes a memory containing image information corresponding to a plurality of authorized users, and is operative to unlock said at least one locking compartment when said visible image matches the stored image data for any of said plurality of authorized users.
3. The medications or anesthesia cart according to claim 1 ,
wherein said sensor means to receive a user command includes an audio pickup adapted to receive an audible spoken command of the user, and a speech recognition functionality in said computer processor adapted to receive said audible spoken command of said user and recognize and interpret said spoken command and wherein a predetermined spoken command is operative to commence opening said at least one locking compartment.
4. The medications or anesthesia cart according to claim 3 ,
wherein the speech recognition facility of said computer processor includes a memory containing speech patterns of a plurality of authorized users, and is operative to commence opening said at least one locking compartment only when the spoken commands match a speech pattern of an authorized user stored in said memory.
5. The medications or anesthesia cart according to claim 4 , wherein said at least one locking compartment includes at least a first locking compartment and a second locking compartment.
6. A medications or anesthesia cart or cabinet comprising:
a cabinet;
a computer control arrangement mounted on or in said cabinet and including a computer processor;
at least one locking compartment in said cabinet including an electro-mechanical lock coupled to said computer processor;
a first camera on said cabinet oriented to obtain an image of a user of said cart and adapted for providing a visible light image of said user to said computer processor;
a second camera on said cabinet oriented to obtain a thermal image of said user of said cabinet and adapted for providing said thermal image to said computer processor;
means on or in said cabinet to receive a user command to commence opening said at least one locking compartment;
said computer processor being further operative to process data in said visible image and data in said thermal image sufficient to ensure that both images represent the face of an authorized user, and permitting said electromagnetic lock to unlock said at least one locking compartment when the visible image represents the face of a given authorized user, but operative to block the at least one locking compartment from opening when the thermal image does not correspond to a human face;
wherein said sensor means to receive a user command includes an audio pickup adapted to receive an audible spoken command of the user, and a speech recognition functionality in said computer processor adapted to receive said audible spoken command of said user and recognize and interpret said spoken command and wherein a predetermined spoken command is operative to commence opening said at least one locking compartment,
wherein the speech recognition facility of said computer processor includes a memory containing speech patterns of a plurality of authorized users, and is operative to commence opening said at least one locking compartment only when the spoken commands match a speech pattern of an authorized user stored in said memory wherein said at least one locking compartment includes at least a first locking compartment and a second locking compartment;
and wherein said memory contains speech patterns of a first group of authorized users which are authorized access to said first locking compartment and speech patterns of a second group of authorized users which are authorized access to said second locking compartment.
7. A medications or anesthesia cart or cabinet comprising:
a cabinet;
a computer control arrangement mounted on or in said cabinet and including a computer processor;
at least one locking compartment in said cabinet including an electro-mechanical lock coupled to said computer processor;
a first camera on said cabinet oriented to obtain an image of a user of said cart and adapted for providing a visible light image of said user to said computer processor;
a second camera on said cabinet oriented to obtain a thermal image of said user of said cabinet and adapted for providing said thermal image to said computer processor;
means on or in said cabinet to receive a user command to commence opening said at least one locking compartment;
said computer processor being further operative to compare data in said visible image and data in said thermal image sufficient to ensure that both images represent the face of an authorized user, and permitting said electromagnetic lock to unlock said at least one locking compartment when the visible image represents the face of a given authorized user, but operative to block the at least one locking compartment from opening when thermal image does not correspond to a human face;
wherein said first and second cameras are operative to obtain the visual and thermal images, respectively, of said user of said cart only after said computer processor having received a spoken command to commence opening said at least one locking compartment.
8. The medications or anesthesia cart according to claim 7 , wherein upon said spoken command, said first and second cameras are respectively operated sequentially within a brief predetermined length of time that is less than a time required to substitute a false thermal face for a false image of a face for the user for either of said first or second cameras.
9. The medications or anesthesia cart according to claim 8 , wherein said brief predetermined length of time is substantially one second.
