Claim 5:
6. A computer-implemented method for displaying a value, said computer-implemented method comprising:
(a) providing a housing comprising (i) one or more sensors comprising an ultrasonic sensor, (ii) one or more microcontrollers, and (iii) a display disposed on a surface of said housing;
(b) receiving, by said one or more sensors, an ultrasonic signal corresponding with one or more objects entering a space or exiting said space to produce location data for said one or more objects;
(c) receiving, by said one or more microcontrollers, said location data from said one or more sensors;
(d) calculating, by said one or more microcontrollers, said value, based, at least in part, on said location data received from said one or more sensors in (c);
(e) displaying said value on said display; and
(f) transmitting, by said one or more microcontrollers, said value to a server that transmits said value to one or more electronic devices in wireless communication with said server,
wherein said value comprises a number of said one or more objects permitted to enter said space, and wherein said calculating said value in (d) comprises:
(i) counting a number of said one or more objects in said space based on the location data received in (c); and
(ii) subtracting the number calculated in (i) from a predetermined threshold value, wherein said predetermined threshold value is a maximum occupancy for the space.
