Abstract: A system is provided for detecting a forcer misalignment, e.g., due to forcer loss of registration (FLR), in a wafer prober used for electrical testing of a semiconductor wafer. The system includes an optical sensor system including a transmitter and receiver affixed to the forcer or to a reference structure (e.g., the prober platen), and a reflector affixed to the other one of the forcer or reference structure. The transmitter emits radiation toward the reflector, which reflects the radiation toward the receiver. The receiver detects the reflected radiation, and generates an output signal indicating the quantity of received radiation. Alignment monitoring circuitry is configured to identify a misalignment of the forcer relative to the reference structure (e.g., platen) based on the output signal generated by the receiver, and in response, output an alert signal, e.g., to suspend operations of the prober and/or display an error notification to an operator.

Abstract: Apparatus and methods, and uses of apparatus, for preventing prolapse of iris tissue, through a surgical opening in the eye during eye surgery. Early in the surgery, one or more surgical openings are made in the eye, and a flexible biocompatible iris shield is inserted, through a such opening, into the anterior chamber and placed in a position whereby the iris shield overlies the iris anteriorly, adjacent each surgical opening and is positioned between the iris and any surgical openings. If/when the pressure inside the anterior chamber increases during surgery, any anterior movement of the iris toward the cornea or sclera in response to such pressure, moves the iris shield in an anterior direction, such that the iris shield remains between the iris and the surgical opening. Thus, the iris shield blocks the surgical opening and prevents movement of eye material, e.g. iris tissue, to and through the surgical opening.

Abstract: It is a common belief today real teleportation of large objects, definitely humans, is science fiction; beyond normal (paranormal). The problem with this assessment (even though promoted among noted scientists) teleportation is happening in front of our eyes today. The Chinese published proof by means of a scientific experimentation that teleportation is real as suggested in a USAF Teleportation Report in 2004. Knowledge to teleport was provided by Nikola Tesla 107 years ago and the science to teleport provided by Albert Einstein and Theodor Kaluza 86 years ago. With today's technology it is time to bring real teleportation into reality. It is time to teleport it is time to add another non-physical aspect into our technology, a non-physical intelligence capable of communicating through Einstein's 4th dimension and providing a foundation for a new world of real teleportation.

Abstract: To utilize the most efficient memory available to a mobile processor, page access counters may be used to record utilization associated with multiple different memory types. In one embodiment, an operating system routine may analyze the page access counters to determine low utilization pages and high utilization pages to dynamically assign between the multiple different memory types, which may include a more efficient memory type having greater capacity, greater throughput, lower latency, or lower power consumption than a less efficient memory type. As such, in response to detecting a high utilization page in the less efficient memory or a low utilization page in the more efficient memory, contents associated therewith may be copied to the more efficient memory and the less efficient memory, respectively, and virtual-to-physical address mappings may be changed to reflect the reassignment.

Abstract: Methods and apparatus for voltage scaling are provided. In an example, an operational limit of a processor is determined by varying a supply voltage to force a processor interrupt fault and/or a processor reset. A clock frequency and the supply voltage can be maintained substantially constant for a time duration. If these operational parameters do not force the processor interrupt fault and/or the processor reset, the supply voltage is varied again, and the clock frequency and the supply voltage are maintained substantially constant for a second time duration. The variation continues until initiation of the processor interrupt fault and/or the processor reset, at which time least one of a clock frequency, the supply voltage, and a temperature are recorded as an operational limit. After determining the operational limit, the supply voltage is adjusted to within the operational limit.

Abstract: A benchmarking mechanism numerically analyzing stalls in a pipelined CPU. Each stage in the CPU is instrumented with dedicated stall counters. For each clock cycle and for each CPU stage, the technology described herein determines whether the stage is stalled, counts the number of stalls per stage, determines why the stage is stalled, and determines which instruction is in the stalled processor stage along with its program address.

Abstract: Adaptive voltage scalers (AVSs), systems, and related methods are disclosed. The AVSs are configured to adaptively adjust voltage levels powering a functional circuit(s) based on target operating frequencies and delay variation conditions to avoid or reduce voltage margin. In one embodiment, the AVS includes an AVS database. The AVS database can be configured to store voltage levels for various operating frequencies of a functional circuit(s) to avoid or reduce voltage margin. The AVS database allows rapid voltage level decisions. The voltage levels stored in the AVS database may be initial, minimum, learned, populated, explored, backed out, temperature-based, and/or age-based voltage levels according to disclosed embodiments to further avoid or reduce voltage margin. An AVS module may be a software-based module that consults the AVS database to make voltage level decisions. Providing the AVS module as a software-based module may allow flexibility in configuring the AVS module and/or the AVS database.

Abstract: Apparatus and methods for preventing prolapse of iris tissue through a surgical opening in the eye during an ophthalmic surgery. A flexible biocompatible polymeric shield is inserted into the anterior chamber of the eye, placed in position overlying the iris adjacent a surgical opening into the anterior chamber and is thus between the iris tissue and the surgical opening. As pressure inside the anterior chamber increases during the surgery, anterior movement of the iris toward any surgical opening in response to such pressure, also moves the shield anteriorly, such that the shield remains between the iris and the surgical opening. Thus, the shield blocks the surgical opening and prevents movement of eye material to and through the surgical opening. The surgical opening can still be accessed by surgical tools and materials from outside the eye by inserting such articles through the surgical opening and pushing such articles past the shield.
