摘要:
Laser beam scan line nonlinearity is compensated for by providing algorithms for generating linearity profiles which are used by a corresponding registration system in an electrophotographic device to determine the placement of Pels across a scan line.
摘要:
The dynamic range of an electrophotographic device may be shifted by calibrating a laser power of a laser source to operate within a first range of power levels during a laser power adjustment operation. At least one laser control parameter is modified after calibrating the laser power so that the laser source is operable within a second range of power levels different from the first range of power levels and a beam emitted by the laser source is controlled within the second range of power levels when the beam is directed towards an image area of a photoconductive surface.

Systems and methods are provided for characterizing laser beam process direction position errors in an electrophotographic device. Once the process direction position errors of a given beam laser beam system have been characterized, an image is adjusted or warped prior to being processed by the laser beam system to compensate for laser beam process direction position errors, e.g., bow and skew.
摘要:
A method of minimizing visual artifacts resulting from a laser scan process in an electrophotographic machine, the electrophotographic machine including a photoconductive device having an image forming surface. The method including the steps of obtaining correction data relative to a bowed image and offsetting at least a portion of non-bowed image data dependent upon the correction data, and additionally dependent upon halftone cell growth of a halftone cell.

An optical scanner is provided having a memory device thereon. The memory device may store operational characteristics of the optical scanner or data that characterizes laser beam scan path and/or laser power requirements by each laser of the optical scanner. The memory device may be used to store historical information such as device temperature, cycles of operation and other historical information of components within a corresponding electrophotographic device. Still further, the electrophotographic device to which the optical scanner is installed may write operational data to the memory device, for example, to store a backup of registration and other operational parameters that are typically stored by the controller of the electrophotographic device.

There is disclosed a power drop assembly which includes a housing and a reel positioned and rotatable within it. Preferably, the device determines, not only whether power is available, but how much power is available. Preferably, the power drop assembly also contains a processor and non-transitory storage medium, so that user settings and profiles as well as settings and profiles for the power drop assembly can be stored and run. Additionally, the power drop assembly preferably contains a wireless transceiver which connects to a home Wi-Fi network and then to a cloud account, user profiles and settings, and settings and profiles for the power drop assembly can be saved on the cloud account. In this way multiple users can use the power drop assembly without contradicting instructions or resetting the power drop assembly every time it is used.
摘要:
Devices, systems, and methods for varying rotational speeds is disclosed. A battery pack has a plurality of batteries and a switch. The battery pack has an overall voltage. The switch varies the overall voltage in discrete steps by combining the plurality of batteries in series, in parallel, or in a combination thereof. A motor drives a shaft at a rotational speed. The motor is powered by the battery pack. The rotational speed varies proportionally with the overall voltage.

The present disclosure is directed to systems and methods for tracking application data, the method comprising: having a publisher integrate organic install tracking (OIT) code into its website; enabling a visitor to view or click on a link published on the publisher's website or application that links to an application on an application store or on an application download website; passing, via the OIT code, visitor information to an OIT server, the visitor information including impression information, application detail information, visitor click information and visitor device information; determining, with the OIT server, which portions of the visitor information are to be passed to at least one attribution analytics provider (AAP) as attribution data; passing the attribution data to the application's AAP; allowing a user to visit the application store or application download website to download the application, open the application installer and install the application; matching, with the application's AAP, the user with the visitor click information of the visitor information to record the user as a valid install; and posting the valid install as an install confirmation in the OIT server.
摘要:
The invention is a method for intelligent current limiting enabling chaining of electrical appliances. Different embodiments apply to alternating current (AC) appliances, direct current (DC) appliances, and a combination of each. In each embodiment, current limits control the number of appliances that can be connected in the chain. If current limits are exceeded, current-limiting devices cut power to one or more of the appliances. Each appliance in the system has conductors with the capacity to carry a current load at least as large as the overall current limit. Preferably, the appliances in the system are garage appliances that are mounted to an overhead track system in a garage, where electrical outlets are scarce.
摘要:
An injection device (1) for administering a fixed dose of a medication is provided. The injection device (1) comprises a housing (2) wherein a drive mechanism comprising a drive member (3) is at least partially enclosed and a dosing element (34) which is fixed relative to the drive member (3). Here, a dose can be set by rotating the dosing element (34) relative to the housing (2) in a dose set direction (105) and the dose can be dispensed by pushing the dosing element (34) towards the housing (2). Moreover, a method is provided for operating an injection device (1) for the administration of a fixed dose of a medication: A dose can be set by rotating a dosing element (34), a dose can be dispensed by pushing the dosing element (34) towards the housing (2) and a dose can be cancelled by rotating the dosing element (34) in a direction (106) opposite to the dose set direction (105).
