摘要:
The present invention is a pet cage having an upper cage member and a lower base member. The lower base member has at least two portions: a fixed portion and one or more adjustable portions that can be extended or collapsed as needed. The fixed portion comprises multiple sidewalls arranged in serial to form an enclosed structure except for an opening on one or more sides, where a lip takes the place of a wall that would otherwise enclose the fixed portion of the fixed portion. One or more adjustable portions are located adjacent, and attached to the one or more sides of the fixed portion of the base member. While in a partially or fully extended state, the adjustable portions have fully open or partially open bottoms that provide access for the pet to reach fresh grass underneath the cage or to conveniently clean bedding material.

The present invention is a pet cage having an upper cage member and a lower base member. The lower base member has a bottom that is partially cut out. An exchangeable plate or tray is provided and adapted to engage with the opening in the bottom of the lower base member. When an exchangeable plate or tray with access points, such as through-holes, are used, the pet can graze on fresh grass in a safe environment. When an exchangeable plate or tray without access points are used, the cage is restored to a conventional cage with closed bottom surface.

An adjustable ring having a curved section and two telescoping arms. Each telescoping arm comprises two or more tubes that move relative to each other in a concentric manner between a collapsed state and an extended state to accommodate various amounts of sheet or sheet-like materials. A ring binder can be constructed using one or more of the adjustable rings.

A display system includes a display alignment tracker configured track the position of a first signal in a first waveguide and the position of a second signal in a second waveguide. The display alignment tracker optically multiplexes a portion of a first signal and a portion of the second signal into a combined optical signal and measures a differential between the first signal and the second signal. The differential is used to adjust the position, dimensions, or a color attribute of the first signal relative to the second signal.

A method for implementing full cycle regeneration of a waste lead acid battery is provided. The method includes the following steps. Step (1): the waste lead acid battery is smashed and separated so as to obtain grid lead, diachylon, plastic and waste electrolyte. Step (2): the obtained diachylon after being dried is positioned into an airtight reactor for desulphurization and deoxidation, wherein lead sulfate and the lead dioxide both in the diachylon react to obtain lead monoxide (PbO) and sulfur trioxide (SO3). Step (3): the obtained lead monoxide is reduced by solid phase electrolysis in a wet way so that the lead monoxide is reduced into sponge lead.

A method for mobile underwater acoustic communications includes double differentially (DD) encoding a communication signal to produce a DD-encoded communication signal, applying direct sequence spread spectrum (SS) to the DD-encoded signal to produce a DD-SS communication output signal, and transmitting the DD-SS communication output signal. The method i) increases the SNR via processing gain, ii) eliminates the ISI through multipath suppression, and iii) enables bandwidth efficiency improvement via data multiplexing. The method is shown capable of facilitating simple receiver processing and offering performance robustness against unpredictable channel fluctuations.

The present invention provides an approach and corresponding framework that separates data from its formatting/view by generating the dynamic JavaScript (data) as a set (e.g., at least one) of JavaScript (data) objects, without any HTML formatting. Then, a set of JavaScript functions can be created that takes the set of JavaScript objects as a parameter, and outputs all or a subset of this data object in a format determined by this JavaScript function. In general, these formatting functions can be static, rather than dynamic, JavaScript. This approach has the advantage of providing a much greater degree of formatting flexibility, without the need for each new format to establish a connection with the back-end system providing the data.

Various embodiments related to rear-projection image display are disclosed. For example, one disclosed embodiment provides a projector for projecting an image and a screen configured to display the image. The screen comprises a filter layer having a light reception side and an image display side. The filter layer includes an array of trapezoidal transmissive elements and an array of trapezoidal absorption elements, where a wider base of each of the trapezoidal transmissive elements faces the light reception side of the filter layer, and where a wider base of each of the trapezoidal absorption elements faces the image display side of the filer layer.
