An optoelectronic component has a lens that is formed in the surface of an encapsulant surrounding a semiconductor diode element. With respect to emitters, the lens reduces internal reflection and reduces dispersion to increase overall efficiency. With respect to detectors, the lens focuses photons on the active area of the detector, increasing detector sensitivity, which allows a detector having a reduced size and reduced cost for a given application. The lens portion of the encapsulant is generally nonprotruding from the surrounding portions of the encapsulant reducing contact surface pressure caused by the optoelectronic component. This non-protruding lens is particularly useful in pulse oximetry sensor applications. The lens is advantageously formed with a contoured-tip ejector pin incorporated into the encapsulant transfer mold, and the lens shape facilitates mold release.

An input / output interface receives an access request from a requester. A processor associated with the input / output interface applies a filter operation to select a subset of rules from a master set of rules maintained within an authorization database. Rules can be selected in this manner using filter operations so that all rules in the rule set need not be processed. A rule may include a disregard instruction. The processor further performs at least one rule operation based on the subset of rules to produce an access control decision in the memory system until either a rule operation including a disregard instruction is performed to limit performance of rule operations in the selected set of rules or until all rule operations in the selected set of rules that are applicable to the access control decision are performed.

An atomic layer deposition system and method utilizing radicals generated from a high-density mixed plasma for deposition is disclosed. A high-quality oxide or oxynitride can be deposited by exposing a substrate to a first precursor which is adsorbed onto the substrate during a first phase of one deposition cycle. After purging the deposition chamber, the substrate is exposed to a second precursor which includes oxygen radicals and krypton ions formed from the high-density mixed plasma. The ions and radicals are formed by introducing a radical generating feed gas (e.g., O2) and an ion generating feed gas into a plasma chamber and exciting the gases to form the high-density mixed plasma. The radicals and ions are then introduced to the substrate where they react with the first precursor to deposit a layer of the desired film. Krypton is preferably used as the ion generating feed gas because the metastable states of krypton lead to an efficient dissociation of oxygen into oxygen radicals when compared with other inert gases.

System and methods for flash heating of materials deposited using atomic layer deposition techniques are disclosed. By flash heating the surface of the deposited material after each or every few deposition cycles, contaminants such as un-reacted precursors and byproducts can be released from the deposited material. A higher quality material is deposited by reducing the incorporation of impurities. A flash heating source is capable of quickly raising the temperature of the surface of a deposited material without substantially raising the temperature of the bulk of the substrate on which the material is being deposited. Because the temperature of the bulk of the substrate is not significantly raised, the bulk acts like a heat sink to aid in cooling the surface after flash heating. In this manner, processing times are not significantly increased in order to allow the surface temperature to reach a suitably low temperature for deposition.

Operating system events are monitored and a file change request of a process is detected. If the process is suspicious, then the file to be changed is backed up and then the process is allowed to change the file as requested. If it is later determined that the process is ransomware, the process is blocked and further file backups are halted. The original file is recovered and the encrypted file is discarded. If it is later determined that the process is not malicious, then further file backups are halted. Any backup files are discarded. Ransomware may be detected by comparing a file extension of the process with file extensions of any files requested to be changed, by comparing file extensions of any files requested to be changed, or by an analysis of behavior of the process itself.

Furthermore, since the invention does not use digital image re-sampling, there are no pixel quantization errors to cause false differences between the pattern and image that can limit inspection performance.

A snapshot copy facility maintains information indicating ownership and sharing of child nodes in the hierarchy of a file between successive versions by delegating reference counts to the parent-child relationships between the nodes, as indicated by pointers in the parent nodes. When a child node becomes shared between a parent node of the production file and a parent node of a snapshot copy, the delegated reference count is split among the parent nodes. This method is compatible with a conventional data de-duplication facility, and avoids a need to update reference counts in metadata of child nodes of a shared intermediate node upon splitting the shared intermediate node when writing to a production file.

Accordingly, the pleasant performance of the passenger compartment is improved while fuel economy performance of the engine is improved.
