20100018424 | Devices comprising several spaced-apart storage compartments - At least several spaced apart storage compartments are provided in a plate storage device. These compartments can receive used printing formes from a printing cylinder or new printing formes that are to be supplied to the printing cylinder. At least one positioning assembly is utilized to adjust at least one mouth region of two of the storage compartments to the same spaced position, with respect to the printing cylinder, at different times in the operating cycle of the plate storage compartments. This mouth region is situated facing the printing cylinder. In another embodiment, at least one printing forme, that is being received from the printing cylinder, can be stored in at least one storage compartment. At least one conveying apparatus is provided and includes an entraining mechanism for gripping the printing forme that is to be removed. Alternatively, the conveying apparatus can be used with a new printing forme that is to be fed to the printing cylinder and which is stored in at least one of the storage compartments. At least one advancing mechanism is provided and is comprised of a slider that can grip the printing forme that is to be fed. A positioning assembly lifts and lowers the storage compartment, relative to the entraining mechanism and/or the slider or lifts and lowers the entraining mechanism and/or the slider relative to the storage compartment. | 01-28-2010 |

20150078411 | TUNABLE LASER, A METHOD FOR MAKING, AND A METHOD FOR OPERATING SUCH A LASER - Semiconductor lasers, in particular Quantum Cascade Lasers (QCLs) are tuable especially in the mid-IR spectral range, e.g. in wavelengths of about 3-14 μm, by precisely controlling the laser's temperature in the vicinity of the active region. The present invention introduces a novel design for locally heating the active region, thereby allowing fast heating and thus tuning a laser. It is generally applicable for lasers across the field, e.g. to QCLs with multi-color emitters or to Vertical-Cavity Single-Emitter Lasers (VCSELs) or to Distributed Feedback (DFB) lasers. Essentially, the invention consists of structurally integrating a heating resistor as part of the laser, placed close to the component to be temperature-controlled, i.e. the active region or the grating, etc., and feeding this resistor with a variable electrical current in order to locally control the thermal dissipation. In multi-emitter lasers, a resistor can be associated with each emitter section to tune the temperature of each section and thus its emitted wavelength. Similarly, in multisection DBR lasers, with a resistor associated with each grating, the latter can be tuned and thus the associated wavelength of the optical cavity. The invention also includes a novel manufacturing process, especially for buried heterostructure lasers. | 03-19-2015 |

20130120941 | MODULAR EQUIPMENT RACK SYSTEM FOR DATA CENTER - Various technologies described herein pertain to racking equipment in a data center. A modular equipment rack system can include an upper track, a lower track, a vertical support, a power and network distribution unit, and a tray. The upper track and the lower track can respectively include incrementally spaced mounting locations at which the vertical support and the power and network distribution unit can be attachable. The tray can be attachable to the vertical support and the power and network distribution unit when the vertical support is attached to the upper track at a first upper mounting location and attached to the lower track at a corresponding first lower mounting location, and the power and network distribution unit is attached to the upper track at a second upper mounting location and attached to the lower track at a corresponding second lower mounting location. | 05-16-2013 |
20130295834 | MULTI-CHASSIS CLIMATE REGULATOR PLENUM - Climate regulation within a chassis of an electronics enclosure (e.g., a workstation case or a server cabinet) may be achieved through an airflow regulated by at least one climate regulator devices (e.g., a variable-speed fan array) and a plenum configured to direct the airflow at the components of the enclosure. The enclosure may store a set of chassis, each having a dedicated plenum and climate regulator devices. However, this architecture may be less efficient than an architecture wherein adjacently mounted chassis may connect plenums (e.g., directly connecting an exhaust of one plenum with an inlet of the adjacent plenum) to unify the airflow directed through several chassis. Additionally, the chassis may feature a removable portion of the plenum wall that provides access to the plenum, and the climate regulator devices may be mounted on the removable portion, such that detachment enables withdrawal and servicing of the climate regulator devices. | 11-07-2013 |
20130335907 | TRAY AND CHASSIS BLADE SERVER ARCHITECTURE - In computing scenarios involving an aggregation of multiple computational units into a server or computer set, many architectures may be devised to provide physical storage and logical aggregation of the computational units. Presented herein are variations of one such architecture, comprising a chassis having a set of slots, into which may be inserted a tray storing the computational units of one or more blades. Respective trays and chassis slots comprise a power connector and a network connector that are positioned to connect directly (i.e., without a cable or manual interaction) when a tray is inserted into a slot. The chassis stores a set of power supplies, and may connect each blade with a power supply, optionally providing power routing and failover capabilities. The chassis may also provide a management component that connects to and provides management capabilities of the blades of the trays, power supplies, and climate regulating components. | 12-19-2013 |
20130344794 | CLIMATE REGULATOR CONTROL FOR DEVICE ENCLOSURES - Climate regulation within an enclosure (e.g., a case of a workstation or a rack or cabinet of servers) may be achieved through a climate regulator featuring several selectable climate regulator settings (e.g., a variable-speed fan array). Controllers of such climate regulators often select climate regulator settings based on current conditions inside the enclosure, such as the temperature of one or more processors operating within the enclosure. However, such control fails to account for the climate of air outside the enclosure that is drawn in to provide climate regulation, even though the climate properties of inlet air may significantly affect the effectiveness of climate regulation. Accordingly, a controller of a climate regulator may be configured to detect inlet climate properties of air directed into the enclosure, and to map the inlet climate properties (alone or in combination with other factors) to a selected climate regulator setting for the climate regulator. | 12-26-2013 |
