Abstract: An adaptive controller used in a photoplethysmography sensing system, comprises a plurality of hardware circuits which are configured to: receive a photoplethysmography signal (hereinafter, “PPG signal”) processed; determine whether the PPG signal processed satisfies with a requirement; output the PPG signal processed if the PPG signal processed satisfies with a requirement; and adjust a gain of an amplifier for amplifying the PPG signal and/or a driving signal of a light source if the PPG signal processed does not satisfy with a requirement.

Abstract: A processor-implemented method for simultaneously tracking one or more objects includes receiving, via a dynamical system with a set of sensors, a first set of unlabeled measurements from one or more objects. Each of the measurements is a function of time. A set of candidate tracks is determined for the one or more objects. Probabilities of each of the first set of unlabeled measurements being assigned to each of the set of candidate tracks are computed. A track from the set of candidate tracks is determined for each of the one or more objects based on a joint probability distribution of track attributes and the probabilistic assignment of each of the first set of unlabeled measurements to each of the set of candidate tracks.

Abstract: A method of decomposing a cured aromatic epoxy resin uses a molten salt bath at less than about 350° C. The molten salt bath includes a plurality of alkali metal hydroxides. The cured aromatic epoxy resin can be in intimate physical contact with a metal or alloy. The cured aromatic epoxy resin can be patterned by a lithographic method. The lithographic method can be multibeam interference lithography to form a three-dimensional photonic crystal template on a conductive substrate for electrodeposition of metal. Contacting the three-dimensional photonic crystal template with the electrodeposited metal with the molten salt bath can form a metal matrix device displaying a periodic pattern that is the inverse of the periodic pattern of the decomposed three-dimensional photonic crystal template.

Abstract: A method to control the density of a three-dimensional photonic crystal template involves changing the irradiation time from at least four laser beams to yield a periodic percolating matrix of mass and voids free of condensed matter from a photoresist composition. The photoresist composition includes a photoinitiator at a concentration where the dose or irradiation is controlled by the irradiation time and is less than the irradiation time that would convert all photoinitiator to initiating species such that the density of the three-dimensional photonic crystal template differs for different irradiation times. A deposition of reflecting or absorbing particles can be patterned on the surface of the photoresist composition to form a template with varying densities above different areas of the substrate.

Abstract: Techniques are disclosed for a client-and-server architecture where the client makes scheduled execution of instances to the server. The server may then launch occurrences as indicated by one of these API calls at each of the scheduled times. The server may also implement operations to selectively execute particular occurrences, such as executing a new occurrence only when no other occurrences are still running. In other embodiments, the server may implement pricing information in a determination of whether to execute a particular occurrence.

Abstract: This document describes techniques for performance testing computing resources in a service provider network. In an example embodiment, a performance manager periodically tests the performance of computing devices in the service provider network using selected computing assets of each computing device, and updates, based on the performance, a ranking value that establishes precedence for allocation of resource instances of the computing device. A placement manager assigns resource instances from the computing devices based on the ranking values.

Abstract: A virtual computer system service receives a request to migrate a virtual machine instance from a first physical host to another physical host. The virtual computer system service identifies a configuration of the first physical host and obtains a data structure that specifies compatibility values for pairings of physical host configurations. The virtual computer system uses the configuration of the first physical host and the data structure to select a compatible physical host configuration. Using this compatible physical host configuration, the virtual computer system service selects a set of physical hosts that have this compatible physical host configuration. The set of physical hosts is used to select a second physical host onto which the virtual machine instance is migrated.

Abstract: A technology is described for assigning a logical private network address to a computing instance. An example method may include obtaining a preserved logical private network address associated with a customer account so that the preserved logical private network address may be assigned as a logical private network address to a computing instance located in a computing service environment. The logical private network address may be used for network communications within a physical host containing the computing instance and the logical private network address may translate to a physical private network address used for network communications outside of the physical host and within the computing service environment.

Abstract: Technologies are described herein for providing notifications of computing resource availability for on-demand allocation. A resource request is received from a requesting application indicating the type, size, number, and other parameters of the computing resources desired. Upon determining that the requested computing resources are not immediately available, suitable alternative resources are determined based on the parameters of the requested resources. The availability of computing resources at the service provider is monitored, and when the requested resources or suitable alternatives become available, the requesting application is sent one or more resource availability notifications describing the available resources. The requesting application may then allocate the available resources from the service provider on-demand.

Abstract: Systems and methods are described for managing requests for computing capacity from a provider of computing resources. The computing resources may include program execution capabilities, data storage or management capabilities, network bandwidth, etc. In some implementations, a user can request that computer resources be reserved for guaranteed availability by the user (or others authorized by the user) during a future usage time period. For example, the user can request a desired amount of program execution capacity. The usage period can be flexibly chosen to meet the user's needs. The request can specify, for example, that a particular program be executed during the usage period, that only certain users be authorized to have access to the guaranteed availability computer resources, and so forth. The provider may charge a fee for the request and/or fees for access or use of the guaranteed availability computer resources during the usage period.
