A drive circuit for supplying a drive current to light emitting elements includes an output circuit that sets a magnitude of the drive current based on an assumed value of a threshold current being a threshold value of the drive current, an acquisition circuit that acquires an optical-output monitor value indicating a magnitude of an optical output of the light emitting elements, a first calculation circuit that calculates an average value of the drive current in a predetermined period in a frame period as an average drive current value for each of the predetermined period, a second calculation circuit that calculates an average value of the optical-output monitor values in the predetermined period as an average optical-output monitor value, and an adjustment circuit that adjusts the assumed value of the threshold current value based on the average drive current value and the average optical-output monitor value.

Drive circuit and image projection apparatus

There is provided a determining apparatus which includes a first extractor configured to extract space inside an electronic device from a model indicating the electronic device, the electronic device including a plurality of audio output apparatus and a plurality of ribs, a second extractor configured to extract the plurality of ribs from the model, a divider configured to divide the space into a plurality of chambers, the plurality of chambers being partitioned by the plurality of ribs, and a determining unit configured to determine respective rear chambers to each of the plurality of audio output apparatus so that the rear chambers satisfies a certain parameter, the rear chambers being formed by combination of one or more chambers determined by the determining unit.

Determining apparatus, program, and method

A collision detection unit detects whether a first entry that is associated with a value obtained by hashing a first MAC address is present in each area in a MAC address table and detects whether a second entry that is associated with a value obtained by hashing a second MAC address is present in each area in the MAC address table. If the first entry is present in each of the areas, a collision avoidance control unit acquires the second MAC address stored in the first entry that is present in one of the areas and inputs the second MAC address in the collision detection unit. If the second entry is not present in any of the areas in the MAC address table, a registration unit stores the second MAC address in the second entry and stores the first MAC address in the first entry.
