    Abstract: A liquid cartridge is configured to be inserted into a cartridge-attachment section including a casing and a light blocking portion. The casing includes a liquid chamber; a liquid passage extending in a first direction; and a top surface facing upward. The light blocking portion is deformable between a non-deformed state and a deformed state. The light blocking portion, at least in the non-deformed state, is configured to block or attenuate light emitted from the cartridge-attachment section and traveling in a widthwise direction crossing the first direction and a gravitational direction in an upright posture. The light blocking portion in the non-deformed state is configured to be deformed to the deformed state by an external force. The light blocking portion returns to the non-deformed state when the external force is removed from the light blocking portion in the deformed state.

  • Patent number: 10421284
    Abstract: A liquid cartridge configured to be inserted into a cartridge-attachment section in an insertion direction includes a casing, and a lever supported by the casing. The lever is pivotable about a pivot axis between a first position and a second position. The lever includes a light-blocking portion configured to block or attenuate light traveling in a widthwise direction crossing the insertion direction and a gravitational direction, and a force-receiving portion positioned closer to a front wall of the casing than the light-blocking portion is to the front wall in the insertion direction. The light-blocking portion is positioned lower at the second position than at the first position. The pivot axis is positioned frontward of the light-blocking portion and rearward of the force-receiving portion in the insertion direction. The lever pivots from the second position to the first position upon application of an external force to the force-receiving portion.

  • Patent number: 10408698
    Abstract: A force dynamometer includes at least one plate, a controller with a memory and at least one force sensing resistor that senses a force exerted on the one or more plates. The controller receives a signal indicating magnitude of the force and transmits a signal to at least one color variable light emitting diode (LED) to change color of the color variable LED in response to the force sensing resistor changing magnitude of the force signal transmitted to the controller. The controller may transmit a signal to one or more piezoelectric sensors such that the controller controls intensity of vibrations and/or magnitude of frequency of the vibrations of the one or more piezoelectric sensors. A force dynamometer system includes a computing device that displays or controls speed of a variable motion speed image or object or displays or controls a direction controllable image or object via the force dynamometer.

  • Patent number: 10391778
    Abstract: A liquid cartridge includes: a casing including a liquid chamber; a liquid supply portion; a deformable member; a movable member; and an urging member. An internal pressure of the chamber is reduced as liquid flows out of the chamber. The deformable member protrudes from the casing in a cross direction crossing forward and rearward directions and has an internal space in communication with the chamber. The deformable member has such an elasticity that a dimension thereof in the cross direction becomes smaller as the internal pressure of the chamber is reduced. The movable member includes a detection portion, and a contact portion contacting the deformable member. The contact portion is in contact with the deformable member and disposed at one of positions further forward and further rearward relative to the deformable member. The urging member urges the movable member to move the contact portion toward the deformable member.
