Methods and apparatus to count people are disclosed. Example apparatus disclosed herein include means for discarding existing characteristic datasets from a list; means for populating the list with first characteristic datasets obtained from a first plurality of images representative of an environment during a first period of time of a media presentation; means for limiting a number of the first characteristic datasets stored in the list for a first location represented in the first plurality of images; and means for comparing the first characteristic datasets to each other to determine a first number of unique faces in the environment during the first period of time, wherein the means for discarding is to delete the first characteristic datasets from the list, and the means for populating is to re-populate the list with second characteristic datasets obtained from a second plurality of images representative of the environment.

The present invention is directed to devices that may be used to help young children stay in bed or their room until it is time to get up. The device may be configured as a clock. The clock may be programmable to have a duration of a nap time, or a time when the child is able to get up. A visual countdown timer may be provided with the device (e.g., on the clock face), which may include a graphical representation of the remaining fraction of time before get up time. The visual countdown timer may not include number indicia, but rather includes a graphic (e.g., ring extending about the perimeter of the clock face), which gradually diminishes as the predetermined get up time is approached. A reward drawer may also be provided, which automatically unlocks at the get up time, and provides the child with a prize.

A slotted timer teaches time in a simple manner to those having difficulty understanding the concept of time. The timer rotates a shaft which rotates a colored disk attached to the shaft. The initial position of the colored disk is manually set by an operator using a card residing in a slot extending across the top of the timer. The card may illustrate an activity to be completed in a time period set by the operator. Different cards may be used to indicate different activities.

Methods and apparatus to count people are disclosed. Example people counting apparatus disclosed herein include a difference calculator to calculate a degree of similarity between a first characteristic dataset and a second characteristic dataset representative of face detections in images. Disclosed example people counting apparatus also include a limiter to store the first characteristic dataset and the second characteristic dataset in a plurality of characteristic datasets associated when the degree of similarity does not satisfy a threshold, and to store the first characteristic dataset in the plurality of characteristic datasets and discard the second characteristic dataset when the degree of similarity satisfies the threshold to limit a number of stored characteristic datasets. Disclosed example people counting apparatus further include a comparator to compare the plurality of characteristic datasets to each other to determine a number of unique faces in an environment during a first period of time.

An electronic talking stick has a body having an outer casing, of a size to fit in a user's hand, a power supply powering circuitry within the body, an electronic timer operable within the body, an on/off switch, and an alert mechanism adapted to cause a user-noticeable alert at specific times according to the timer. Upon applying power by the on/off switch, the timer begins to count down from a pre-programmed time, wherein the alert mechanism generates a timed-out alert when the timer reaches zero, and wherein removing power from the circuitry resets the timer.
