According to one embodiment, there is provided a power reception device including: a power reception coil, a power reception unit, a notification unit, and a control unit. The power reception coil receives power from a power supply device in a non-contact manner. The power reception unit causes the received power as a charging current to flow to a load. The notification unit notifies that a relative position of the power reception device to the power supply device is inappropriate. The control unit starts charging by the charging current which is set to a first current value and controls the charging current so as to gradually increase the charging current. If the charging is stopped before the charging current reaches a second current value larger than the first current value, notification is performed that the relative position of the power reception device to the power supply device is inappropriate.

A noncontact power transmission apparatus includes an instrument including a first case, a power reception coil arranged to generate an induced current due to magnetic flux in a first direction intersecting a gravitational direction, and a holder configured to hold the power reception coil at a predetermined distance from an outer surface of the first case in the first case. A power transmission device includes a conductive second case that has an opening into which the instrument is inserted in which the instrument is stored, a power transmission coil provided in the second case so as to generate magnetic flux in the first direction, and disposed to generate an induced current in the power reception coil, and an elastic body that is provided in the second case, maintains a distance between the power transmission coil and the power reception coil to be constant, and supports the power transmission coil.

A level change point detection section detects a level change point, at which an output level switches, in a first position detection signal Ens1 generated by an encoder or a second position detection signal obtained by increasing the resolution of the Ens1. Each time a predetermined number of level change points is detected, an energization timing determination section determines the timing, at which the predetermined number of level change points have been detected, to be an energization timing for the thermal head.

A printing system includes: a printing device including a thermal head, a supplier, a winder and a ribbon transport mechanism; a moving mechanism moving the printing device in a width direction of an ink ribbon; and a controller configured to: move the printing device in the width direction; when the printing device is moved for printing of a second row, rewind the ink ribbon; store the longest length of use of the ink ribbon by the printing in a first column of the ink ribbon; when printing with the thermal head proceeds to a second column, determine a transport amount of the ink ribbon based on the stored length; and after the first column of the ink ribbon is used by the printing, transport the ink ribbon based on the determined transport amount.

A thermal printer has a thermal head with multiple heat elements for printing on roll paper; a measurer that measures heat element resistance; printer memory storing a resistance evaluation table relating the resistance of the heat elements to heat element defect levels defined based on a specific range of reflectivity in the symbol image; and an evaluator that references the resistance evaluation table stored in printer memory, acquires a defect level based on the resistance measured by the measurer, and evaluates the defect state of the thermal head based on the defect level of a consecutively adjacent count of heat elements.

A fluid ejection device including a plurality of primitives each having a same set of addresses and including a plurality of fluid chambers, each fluid chamber corresponding to a different address of the set of addresses and including a firing mechanism. Input logic receives a series of fire pulse groups, each fire pulse group corresponding to an address of the set of addresses and including warming data having an enable value or a disable value and a series of firing bits, each firing bit corresponding to a different primitive and having a firing value or a non-firing value. For each firing bit of each fire pulse group, when the warming data has the enable value, activation logic provides a warming pulse to the firing mechanism of the fluid chamber corresponding to the firing bit when the firing bit has the non-firing value.
