A system, method and apparatus for notifying a surgeon of an occlusion in an ocular surgical apparatus are disclosed herein. Through operation of a handpiece of the surgical apparatus, the handpiece may become blocked or occluded. An occlusion detector is configured to sense the occlusion in the handpiece, and an occlusion signal is generated. A control module is provided to send an occlusion warning signal to a foot pedal of the surgical apparatus, where a tactile notification is provided to a user of the apparatus that an occlusion has occurred.

In one example, a pedal device includes a base element, for example, to be arranged in a footwell, and a pedal element which is pivotably moveable with respect to the base element. The pedal element is connected to the base element via a hinge. The hinge includes a belt band having a first section and a second section. The first section is fastened to the base element and the second section is fastened to the pedal element. A particularly simple and cost-effective pedal device having stable articulation can be obtained due to the use of a belt band.

A vehicle brake assembly includes an actuation lever coupled to a brake pedal. The brake assembly also includes a push rod of a brake booster. The push rod has a clevis on an end portion thereof. The clevis comprises two prongs. The brake assembly further includes an alignment device seated on each respective prong of the clevis. The alignment devices are configured to collectively guide and position the clevis into alignment with the actuation lever during construction of the brake assembly.

The footwear-protecting gear shift cover is a semi-rigid structure. The footwear-protecting gear shift cover is configured for use with a motorcycle. The motorcycle is further defined with a gear shifting pedal. The gear shifting pedal is further defined with a lever and a crank. The footwear-protecting gear shift cover attaches to the gear shifting pedal of a motorcycle. The footwear-protecting gear shift cover attaches to the crank of the gear shifting pedal. The footwear-protecting gear shift cover comprises a protective structure and a motorcycle. The protective structure is a rectilinear block structure. The rectilinear block structure of the protective structure comprises two parallel planar surfaces in diametric opposition.

A vehicle pedal assembly comprising a pedal housing. A rotatable pedal includes a drum extending into the pedal housing. The drum includes a friction contact surface. A pedal friction pad extends in the pedal housing and includes a pedal friction surface in contact with the friction contact surface on the drum. The pedal friction surface is shaped and positioned to provide for a line frictional contact between the pedal friction surface and the drum. In one embodiment, the pedal friction surface in contact with the drum is arc-shaped. In one embodiment, the pedal friction surface includes a first curved converging segment, the arc-shaped surface segment defines the second surface segment and extends between the first and a third straight converging segment.

Embodiments herein are directed to a pedal pad assembly that includes a housing, a pedal pad, at least one link member, at least one sliding member, and a sensor. The pedal pad is coupled to the housing and configured to translate the housing along a first movement axis in response to a load applied to the pedal pad. A proximal end of the at least one link member is coupled to an outer surface of the housing. The at least one sliding member is coupled to a distal end of the at least one link member. The sensor is configured to sense a position of the at least one sliding member along a second movement axis. During a translation of the housing along the first movement axis, the proximal end of the at least one link member moves translating the at least one sliding member about the second movement axis.

An alignment device may include a saddle element configured to sit on a pedal arm of a brake assembly. The saddle element may include first and second U-shaped ends configured to receive the pedal arm. The first and second U-shaped ends may be spaced apart from one another by an opening defined by first and second lateral wing elements. The first and second lateral wing elements may form a catchment area configured to guide and position a push rod of a brake booster into alignment with the pedal arm.

A pedal assembly includes a housing having a cavity. A pedal arm is at least partially received in the cavity. The pedal arm is configured to move within the cavity relative to the housing. At least two pivot levers are positioned within the cavity and configured to pivot upon a contact by the pedal arm. A spring retainer is formed in the housing. The spring retainer has a spring positioned therein. A spring member is disposed about the spring retainer and is moveable about the spring retainer. At least two sensors are attached to the spring housing. At least two sensor assemblies are positioned in the housing and configured to sense an amount of travel of the at least two sensors. When a load is applied to the pedal pad, the pedal arm contacts the at least two pivot members pivoting the pivot members and moving the spring housing wherein the sensors movement is sensed by the respective at least two sensor assemblies indicative of the amount of depression of the pedal pad.

Embodiments herein are directed to a pedal assembly. The pedal assembly includes a housing, a pedal arm, at least one elongated member, and at least one strain gauge sensor. The pedal arm has a pedal pad on one end. The at least one elongated member is positioned within a cavity and configured to deflect upon a movement by the pedal arm caused from a load applied to the pedal pad. The at least one strain gauge sensor is positioned in communication with the at least one elongated member and configured to sense an amount of the deflection of the at least one elongated member. When the load is applied to the pedal pad, the pedal arm moves and deflects the at least one elongated member, which is sensed by the respective at least one strain gauge sensor indicative of an amount of load applied to the pedal pad.
