Proximity Detection for Electronic Contact Tracing

Completed
We are developing performance metrics for not just ranging, but also for detecting close contacts, which in the context of COVID-19 is the situation where two people are less than six feet apart with no obstacles between them. Obviously, the duration of a close contact is important, as it affects

Public Health Risks to First Responders

Ongoing
This project advances tools and methods to analyze per- and polyfluoroalkyl substances (PFAS) in firefighter gear and workplaces, supporting the development of standards, policies, and best practices to reduce firefighter PFAS exposure.

Public Safety 700-MHz Broadband Deployable Systems

Ongoing
The Middle Class Tax Relief and Job Creation Act of 2012 (H.R. 3630) appropriated $7 billion for the establishment of a nationwide interoperable public safety broadband network (PSBN) under FirstNet, an independent authority in the National Telecommunications and Information Administration (NTIA)

Public Safety 700-MHz Broadband Modeling and Simulation

Ongoing
The Middle Class Tax Relief and Job Creation Act of 2012 (H.R. 3630) appropriated $7 billion for the establishment of a nationwide interoperable public safety broadband network (PSBN) under FirstNet, an independent authority in the National Telecommunications and Information Administration (NTIA)

Public Safety Audio Quality

Ongoing
The audio codec (also called speech codec, voice coder, or vocoder) is a key hardware/software component in every digital radio or handset. At a transmitting location, the codec processes incoming audio into a concise digital representation for efficient transmission over the air. At the receiving

Public Safety Broadband Cybersecurity

Ongoing
Along with the implementation of a nationwide public safety broadband network based on Long Term Evolution (LTE) technology, the network’s cybersecurity capabilities and features will be unique compared to traditional commercial mobile carriers due to public safety’s operational environment and

Public Safety Broadband Requirements and Standards Project Description

Ongoing
PSCR has actively participated in the requirements gathering and standards development process for public safety communications since its inception in 2007. "The PSCR (Public Safety Communications Research) staff ... has traveled the world over, going to 3GPP meetings and going from a point where we

Public Safety Communications Program

Ongoing
America’s first responders deal with emergencies every day. And whether it is a routine traffic stop, a multi-alarm fire, or a large-scale event, such as Hurricanes Harvey and Sandy, or the attacks on 9/11, the ability of first responders to communicate with each other--on-scene as well as through

Public Safety Communications Research

Ongoing
Too often in critical situations communications the data exchanges between law enforcement and public safety agencies are hampered by equipment incompatibilities. In large part these incompatibilities are due to a lack of standards to provide a common, nationwide approach to telecommunications and

Public Safety Image Quality

Ongoing
Here is our plan in a nutshell: Ask how first responders how their department uses photos and video Collect images that demonstrate the many ways first responders use photography Identify patterns—image and video quality problems that impact many first responders Stimulate innovation on novel camera

Public Safety Mobile Application Security

Ongoing
The nationwide public safety broadband network will provide first responders with modern access to data. This new access to multimedia (audio/video), situational awareness data, and operations functionality will enhance first responder’s effectiveness and efficiency. While mobile applications can

Publishing Services

Ongoing
The NIST Research Library occupies the unique position of serving NIST both as publisher of the NIST Technical Series, and in an archival capacity, responsible for collecting and preserving copies of NIST's grey literature. Over the last 15 years, the Library's publishing services have evolved from

Pushing the Limits of Measurement Accuracy in Atom Probe Mass Spectrometry

Ongoing
Isotopic Analysis for Isotopic Geochemistry, Nuclear Safety, and Materials Science : Atom probe tomography has a significant advantage over other forms of mass spectrometry, which typically have a combined efficiency < 5%, in terms of ionization and detection efficiency. Commercial atom probe

Qualification for Additive Manufacturing Materials, Processes, and Parts

Completed
Objective: Develop test methods and protocols, provide reference data, and establish requirements to reduce the cost and time to qualify AM materials, processes, and parts. Technical Idea: Qualification of AM materials, processes, and parts is critical to enabling the AM industry to crack into the

Qualification for AM Feedstocks, Machines and Processes

Completed
Objective - To develop, utilize, and analyze test methods and protocols for characterizing the feedstocks, machines, and processes in metal-based additive manufacturing to enable optimum usage and to reduce the cost and time needed for qualification. What is the Technical Idea? Qualification of AM

Quality Assessment of Cryogenic Electron Microscopy Images

Ongoing
Manufacturing a vaccine based on packaging mRNA in lipid nanoparticles requires a full characterization of concentrations and distributions of mRNA and LNPs, as well as all manufacturing conditions. Such experiments generate hundreds of terabytes (TBs) of images and pose challenges on trusted

Quantification and Characterization of Plastic Additives

Ongoing
Plastic products are not “pure polymers'' as they consist of up to 70% additive chemicals by weight. Plastic additives are mixed into the polymer matrix during production to enhance functional properties, performance, or appearance of the plastic product. The use of additives in plastics is

Quantifying the environmental contributions to mass change

Ongoing
Experiments using two types of centimeter scale oscillators are described: the double paddle oscillator (DPO) and a commercial quartz crystal microbalance (QCM). Double Paddle Oscillator (DPO) Since mass changes are mostly on the surface of mass artifacts, we have implemented a micro-weighing sensor

Quantifying Uncertainty in Accelerometer Sensitivity Studies

Ongoing
DESCRIPTION: International Key Comparisons are performed. The key comparison reference value for charge sensitivity as a function of frequency and the accompanying uncertainty are the principal objectives of these studies. In a suggested mixed effects model several methods for evaluation of this

Quantitative, Cell-based Immunofluorescence Assays

Completed
Analysis of signaling events within individual cells with microscopy imaging has several advantages over non-imaging techniques. The principal advantage of imaging cytometry over plate reader assays and even other single cell techniques such as flow cytometry is the potential for collection of

Quantitative Flow Cytometry Measurements

Ongoing
Flow cytometry is an essential tool for: basic biotechnological and immunological research, the clinical discovery of potential therapeutics, development and approval of drugs and devices, disease diagnosis, and therapeutic treatment and monitoring For example, flow cytometry is commonly used in pre

Quantitative Information from Images

Ongoing
Projects: Quantifying Amount of Material through Light Measurement Fluorescence and Luminescence Imaging for Surgical Guidance Fluorescence-guided imaging devices are being used for navigation in minimally invasive surgical procedures to increase a patient’s positive clinical outcomes and shorten
