Automated Drug Dispenser Based On Pressure Ejection Of Medications, Harshit Kumar, Shekhar Mishra, Uttam Mishra

Defensive Publications Series

Various types of automated drug dispensers exist in the market. However, they usually involve extraction of medications from their packaging and their temporary storage in internal bins. In this paper, we propose a different approach which can bypass this step through pressure ejection of medications (especially capsules) from their packaging strips. Further, it is proposed that a relevant consensus between various pharmaceutical manufacturers for standardization of the size and packaging of medications can allow for increased automation in the dispensation of medications to patients without altering the logistics of the existing manual dispensation of medications.

Explainable Server Cooling Schedule Prediction Using Machine Learned Model Conditioned On Multimodal Data, D Shin

Defensive Publications Series

Server cooling management frameworks that utilize neural networks are trained with a stream of multimodal sensor data, However, model predictions from such models lack explainability. This disclosure describes a fine-tuned model conditioned on multimodal sensor data to perform cooling schedule prediction. The model can also provide explainability by responding to natural language queries. The approach utilizes a transformer decoder architecture, with the model conditioned on multimodal sensor data from a natural server environment. The conditioning enables localizing the understanding of a language model to the specific context of use for server cooling scheduling decisions.

Wlan Evil Twin Detection And Avoidance At Re-Connection, Hp Inc

Defensive Publications Series

An ‘Evil Twin’ is a fraudulent Access Point (AP) setup by a malicious actor to masquerade the legitimate AP to gain access to sensitive information. There is no definitive solution to reliably identify and evade connecting to an Evil Twin. In general, an Evil Twin sends a ‘De-authentication’ Management frame to the client Station (STA). Subsequently, when the client STA tries to reconnect to the network, the Evil Twin lures the STA to establish a connection with it thereby potentially gaining access to sensitive private information. Users commonly use the ‘Auto-Reconnect’ feature which makes them oblivious of whether the STA …

Visual Odometry Using Generative Artificial Intelligence, Lenord Melvix Joseph Stephen Max

Defensive Publications Series

Visual odometry involves the use of a sequence of images for navigation. Visual odometry relies on registering and optically following key points as they move across the sequence of images. The reliability of this procedure degrades when the images include dynamic objects or occlusions. This disclosure describes the use of generative artificial intelligence techniques to improve key point registration and visual odometry in severely occluded environments. Dynamic objects occluding a scene are identified and removed. The removed portions are filled in using generative artificial intelligence. In addition to conventional key points located on non-occluded sections of the image, synthetic key …

Item Identification Via Ultrawideband Trilateration For In-Store Self-Checkout, D Shin

Defensive Publications Series

In-store shopping can involve lengthy wait times due to long checkout lines. While self-checkout counters can be useful, these require customers to manually scan items they want to purchase. This disclosure describes the use of ultrawideband trilateration to automate identification of items that a customer intends to purchase. A store performs a calibration exercise to map physical spaces (e.g., aisles and shelves) to different items for sale. A customer carrying an ultrawideband-capable device can initiate purchase by suitable action, e.g., via a UI element on their device. Ultrawideband trilateration is performed to determine the location of the customer device and …

Image Steganography To Determine If An Image Was Generated By A Generative Model, Lenord Melvix Joseph Stephen Max

Image watermarks, manual inspection, or machine learning techniques to inspect images do not produce conclusive evidence in this regard. This disclosure describes techniques to embed information about the generative model that generates an image and an associated token ID and session information …

On The Fly, Informal Credit Using Digital Payment App And Digital Credit Book, Ankit Aggarwal

Defensive Publications Series

When a preexisting trust relationship exists between a merchant and a customer, e.g., as is common for neighborhood stores, merchants may extend informal credit to known customers. Such credit is typically recorded in physical credit books, since the effort to create and maintain credit entries may be onerous for the merchant. However, such practices may not allow merchants to correctly gauge risk and can also suffer from a trust deficit since the customer does not have access to the merchant’s credit book. This disclosure describes a form of payment that a customer can use to avail informal credit from a …

Rssi Values For Sensing Events Of Interest Including Motion Detection, Yik Hei Ngan, Geoffrey Anders, Dean Kawaguchi

Defensive Publications Series

Aspects described herein relate to systems for detecting movement using “Received Signal Strength Indicator” (RSSI) values. Such values may be collected for various events over a short period of time in an environment and used to generate baseline histogram distributions. These distributions, in turn, may be used to categorize activity in that environment. In some instances, these distributions may be used to train statistical classifiers or machine learning models to learn and identify categories of activities given the baseline distributions. Thus, the RSSI values collected over a short period of time may be used to detect motion without requiring additional …
