Abstract: A computer-implemented process of tracking events is carried out by detecting that a first badge is within a predetermined range of a second badge, thus designating an encounter, and performing, by processor executing instructions read out from memory, an event logging transaction responsive to the encounter. The event logging transaction is performed by receiving, from the first badge, an electronic message characterizing an observation made by the user of the first badge relative to a user of the second badge, converting the electronic message received from the first badge into a pinpoint response, and generating an event record comprising an identification of an event type, and the pinpoint response.

Abstract: According to the embodiments described herein, system and methods for determining relative pose of materials handling vehicles in an industrial environment may include utilizing ultra-wideband (UWB) antenna array systems respective mounted on the materials handling vehicles to send mutually received information to determine the relative pose between the vehicles, determining one or more fields of each materials handling vehicle, and determining one or more overlapping fields between the materials handling vehicles based on the determined one or more fields and the relative pose. A vehicle control may be implemented based on the determined relative pose and the overlapping fields as a field enforcement, such as a control action to avoid collision between the vehicles.

Abstract: A spacer assembly and method for using same to fix a first component to a second component are provided. The method includes positioning the first and second spacer segments between the first and second components, the first and second spacer segments each including an inner face, an opposite outer face, and an exterior surface extending along a longitudinal axis between the inner face and the outer face. The exterior surfaces of the first and second spacer segments are coaxially aligned and secured by a securing device such that the inner faces of the first and second spacer segments define supplementary non-perpendicular angles relative to the longitudinal axis and the outer faces of the first and second spacer segments are parallel to one another. The securing device and the first and second spacer segments are removed after the first component is mechanically coupled to the second component.

Abstract: A materials handling vehicle technology monitor receives wirelessly, from a fleet of materials handling vehicles, electronic vehicle records. Each electronic vehicle record includes technology feature data recorded by a controller on an associated materials handling vehicle. Typically, the electronic vehicle record is generated in response to a corresponding technology feature on the materials handling vehicle being operated in a work environment. Moreover, each electronic vehicle record includes an operator identification of an operator of the materials handling vehicle at the time the technology feature data is recorded. The monitor also generates for each operator, an electronic measurement based upon a comparison of expected technology feature usage, e.g., a threshold, compared to the technology feature data in the received electronic vehicle records, which are associated with the corresponding operator. The process further comprises outputting to a dashboard, a graphical representation of the generated measurements.

Abstract: Testing operational characteristics of a remote control device associated with a materials handling vehicle can include waiting for receipt of a first input indicative that a first button of the remote control device has been pressed, wherein the first button comprises a travel button of the remote control device. The testing may further comprise waiting for receipt, subsequent to receiving the first input, of a second input indicative that at least a second button of the remote control device has been pressed, wherein the second button relates to a first auxiliary vehicle function. The testing still further comprises determining whether or not a predetermined button pressing sequence is successful based at least in part on receiving or not receiving the first and second inputs; and optionally driving a display on the vehicle to provide a visual indication that the button pressing sequence is successful or not successful based on the determination.
