Abstract: A cloud-based system for monitoring food storage/processing comprising at least one fixed sensor to collect fixed location environment data; at least one handheld sensor to collect mobile location environment data; and a remote monitoring and reporting system to collect the fixed and remote location environment data and to audit the collected data. A portable device comprises a processor configured to: receive the mobile location environment data; and transmit an auditable version of the received mobile location environment data to the remote system. A hub device comprising a processor configured to: receive the fixed location environment data; and transmit an auditable version of the fixed location environment data. The monitoring and reporting system is configured to determine whether the version of the environment data indicates that the monitored environment is operating within the bounds of a model defining correct operation of a food process and to output an alert if necessary.

Abstract: We describe a cloud-based system for monitoring food storage/processing. The system comprises: at least one fixed sensor for installation in an environment to be monitored, configured to collect fixed location environment data relating to the monitored environment; at least one handheld sensor for a user to collect mobile location environment data relating to the monitored environment; and a remote monitoring and reporting system located remote to the monitored environment, to collect the fixed location environment data and the mobile location environment data from the fixed sensor and handheld sensor respectively, and to audit the collected data as coming from the fixed sensor and the handheld sensor.

Abstract: According to aspects of the embodiments, there is provided methods of dynamically focusing an LED print bar or printhead using piezoelectric stacks. The stack is mounted on either end of the LED bar to adjust the focus of the bar against the photoreceptor surface. The piezo level could be either controlled through active feedback of some description such as optical or electrical, or as a service or manufacturing input. With electronic control, focus adjustments can be made by the machine, and dynamically, if needed. In one embodiment, a flextensional cell structure is employed to amplify the movement of the piezo stack to move the LED bar in the order of >50 microns closer or away from the photoreceptor surface.

Abstract: An illuminator includes a light guide having a light source that is configured to emit light along a length of the light guide. The light guide further includes outcoupling zones affixed to a rear portion of the light guide, each zones affixed a predetermined distance from each other zone, which are configured to direct at least a portion of the emitted light. The light guide also includes a first diffuser that corresponds to a front portion of the light guide, and which operates to diffuse emitted light exiting the front portion of light guide. The illuminator further includes a secondary diffuser that is located a predetermined distance from the front portion of the light guide forming an air gap there between. The secondary diffuser is configured to further diffuse the at least a portion of the emitted light diffused by the first diffuser after passage through the air gap.

Abstract: An integrated device enables a customer replaceable unit used within an ink jet printer to be enclosed within an enclosing structure as the unit is removed from the printer. The enclosing structure traps debris that may disburse from the customer replaceable unit as it is removed from the printer. The integrated device includes an extendable cover that encloses the customer replaceable unit in response to one end of the cover being moved away from the other end.
