Abstract: An optical imaging lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element arranged in order from an object side to an image side along an optical axis. Each lens element has an object-side surface and an image-side surface. The image-side surface of the first lens element has a concave portion in a vicinity of the optical axis; the object-side surface of the second lens element has a convex portion in a vicinity of the optical axis; the image-side surface of the second lens element has a concave portion in a vicinity of a periphery of the second lens element; and the second lens element has positive refracting power.

Abstract: A file commenting method includes displaying file content in an instant messaging client, displaying comment content entered via a commenting operation performed on a portion of the file content, and displaying a session page when the commenting operation is completed, the session page including the portion of the file content, the comment content, and a file identifier corresponding to the file content.

Abstract: An image signal processor, comprising an input module for obtaining input data from a camera, whereby the camera is arranged to capture a representation of a real-world environment. The image signal processor further comprises at least one adjustment module for compressing the input data and producing compressed input data, and a localization and mapping module arranged to generate one or more data points from the compressed input data. The image signal processor also comprises an output module for outputting at least the one or more data points.

Abstract: A powered pallet truck is provided having a base support portion and a load lift portion. The powered pallet truck has a lift cylinder device connected at a lower portion to a forward extending lift cylinder device seat on the base frame and pivotally connected at an upper portion within a recessed channel in the load lift frame.

Abstract: A pallet truck is provided having an electrical system that reduces wear and the likelihood of fracture of the control wiring and output cable by having a controller to which they are connected also be mounted to the steering mechanism that rotates relative to a base support portion of a truck frame, and a hydraulic power unit that permits a reduced size and height, with a manual hydraulic cylinder and cylinder body at a substantially similar height, and the cylinder body and oil storage cavity in a concentric arrangement.
