Abstract: Light mapping devices and systems for use in indoor or vertical farming are disclosed herein. In particular, a light detection device is provided that includes a plurality of light sensors configured for detecting light emitted from one or more light sources at distinct positions across a grow plane. The light detection device will also include a microcontroller and one or more signal routing circuit boards, or junctions, for making electrical connections between the light sensors and the microcontroller in a multiplex architecture to enable the microcontroller to cycle through and read the Lux values from each of the light sensors with sub-second frequency and in real-time. The light detection device may also be part of a light mapping system that converts the Lux values to PPFD and generates a heatmap of PPFD intensity at distinct locations across the grow plane.

Abstract: Network resources are subject to automated downloading of information by automated-agents that cause business- or user-specific data to be compiled en masse. In order to control resources and information available to automated-agents, markup documents or elements of markup documents are obfuscated such that a client must reconfigure the obfuscated information in order to display the requested content contained in the document. The obfuscation is applied such that the content will render and display to a human user in the same manner as if the element was untransformed; however, the markup will appear syntactically different to an automated-agent. Thus, in response to a user request, a server can transform elements of a structured document and provide the transformed document to the client for reconfiguring and rendering.

Abstract: Service providers may operate one or more services configured to detect requests generated by automated agents. A CAPTCHA may be transmitted in response to requests generated by automated agents. The CAPTCHAs may be included in a modal pop-up box configured to be displayed by a client application displaying a webpage to a customer of the service provider. Furthermore, the CAPTCHAs included in the modal pop-up box may be rendered inactive and caused not to be displayed by client application executing the webpage. Submitted solutions to CAPTCHAs may be presented with a cookie that enables access to resources of the service provider without restriction. Cookies may be tracked and their use may be used to detect automated agent activity.

Abstract: Online retailers may operate one or more services configured to detect requests generated by automated agents. A CAPTCHA may be transmitted in response to requests generated by automated agents. The CAPTCHAs may be included in a modal pop-up box configured to be displayed by a client application displaying a webpage to a customer of the online retailer. Automated agents receiving the CAPTCHAs may not be blocked or otherwise restricted from the resources requested and therefore may not be configured to interact with the CAPTCHAs contained in the modal pop-up box.

Abstract: A method and apparatus for transmitting an analog signal over an optical fiber cable is disclosed. A semiconductor laser provides an optical carrier signal, the laser having the natural linewidth at high power of the same order as the SBS linewidth. The method comprises directly modulating the current of the laser with a dither signal comprising a first component f.sub.C and a second component f.sub.S. Due to the nonlinearity of the "I-V" characteristic of the laser, a thermal modulation component f.sub.T appears in the active region. This thermal modulation component reshapes the spectrum of the semiconductor laser to increase the threshold of the SBS. As a result, the energy of the signal transmitted over the optical cable may be increased by approximately 16 dB. The first frequency is at least twice the maximum frequency of the analog signal and the second frequency is selected to obtain f.sub.C -f.sub.S =f.sub.T.

Abstract: An apparatus for displacing a continuous flat sheet of material having a first edge and a second edge, running along a first plane in a first direction which is the direction of its centerline to a parallel but sideways displaced direction in a second plane the direction being parallel to the first, in which the second edge of the sheet is displaced from the first plane to decrease the path length in the first plane of the second edge relative to the first edge to produce a first change in direction of running and subsequently to displace the first edge from the second plane to decrease the path length in the second plane of the first edge relative to the second edge to similarly produce a second change in direction of running equal in magnitude but in an opposite direction to the first change in direction so that the final direction of running is parallel to the first direction of running.

Abstract: A semiconductor varactor diode of the hyperabrupt junction type, typically having a PNN+ configuration, is disclosed. The impurity concentration in the intermediate N-type portion is grown in by the molecular beam epitaxy process to provide the hyperabrupt profile. Also, the N-type background doping in the P-type zone is minimized by the same epitaxial process to reduce the level of impurity compensation needed.
