Abstract: A merchandise sales system that simplifies the purchase action of the customer is provided. This merchandise sales system constructs a merchandise sales system provided with: a portable terminal capable of reading a two-dimensional code; a member information management server that manages preregistered information related to a member; an authentication server that converts information related to billing referred to when a commodity is purchased (billing information) into a two-dimensional code; and a display device that displays the two-dimensional code.

Abstract: An information processing apparatus includes: a snooze button; an alarm stop button; an alarm processing unit that outputs the alarm at alarm time to be scheduled get-up time, resumes the alarm when manipulating the snooze button during the alarm after suspending the alarm for a predetermined period, stops the alarm when manipulating the alarm stop button during the alarm, and stops, when manipulating the alarm stop button during the suspension of the alarm, resuming the alarm after suspending the alarm; a computing unit that calculates, when stopping the alarm or stopping resumption of the alarm at the alarm processing unit, a get-up index based on the number of times to manipulate the snooze button from the start of the alarm to the manipulation of the alarm stop button; and a registration unit that registers the get-up index as the information to be browsed in the server.

Abstract: A control circuit receives the digital input data of n-bit and controls horizontal drivers so as to provide a liquid crystal panel with voltage corresponding to the input data during a 1H cycle based on standard voltage. In addition, the control circuit creates gradation data by inverting each bit of the input data and controls the horizontal drivers so as to provide the liquid crystal panel with voltage in response to the output gradation data during the subsequent 1H cycle. In this case, gradation-? correction voltage relation is symmetrical with respect to a point in the center between the top gradation step and the bottom gradation step.
