Design and electron optics performance of a MEMS electrostatic electron monochromator
arXiv:2606.09423v1 Announce Type: new Abstract: Monochromators are routinely used in Transmission Electron Microscopy and Electron Energy Loss Spectroscopy, to improve both spatial and energy resolution. State-of-the-art monochromators, however, are complex instruments that typically require additional electron optical correctors, limiting their implementation to the high-end, most expensive microscopes. Miniaturized monochromation relying on purely electrostatic fringe fields has recently...
Design of an efficient Tunable Dual narrow-band MEMS Mid and Far IR emitter with Me-NTA for Industrial and Biomedical applications
arXiv:2606.05838v1 Announce Type: new Abstract: Spectrally selective infrared (IR) thermal emitters are gaining much attention now-a-days for sensing, spectroscopy and biomedical applications. In this research, two metasurface incorporated IR emitters are proposed and numerically analyzed using finite element method (FEM).
Attitude-Aided Linear Calibration of Triaxial Accelerometers
Announce Type: new Abstract: Triaxial MEMS accelerometers are widely used for inertial sensing, navigation, and sensor fusion, but existing calibration methods often rely on costly reference setups or nonlinear iterative optimization, limiting their efficiency and applicability to low-cost or self-calibrating systems. We present attitude-aided linear accelerometer calibration (ALAC), a method that operates on any platform providing orientation information, such as turntables, robotic arms,...
eMEM: A Hybrid Spatio-Temporal Memory System For Embodied Agents
Announce Type: new Abstract: We present eMEM (Embodied Memory), a hybrid graph-based memory system for embodied agents operating in physical environments. Current agent memory architectures, such as Generative Agents, MemGPT, and A-MEM, treat memory as text streams or knowledge graphs, but embodied agents require memory that is simultaneously searchable by meaning, space, and time. eMEM fills this gap with a multi-index architecture (SQL ITE for structured storage, hnswlib for approximate...
AURA: Action-Gated Memory for Robot Policies at Constant VRAM
Announce Type: new Abstract: The KV-cache is the right memory for datacenters but the wrong memory for robots. Datacenter inference batches many short requests and resets them, amortizing an attention cache across a crowd. Embodied agents instead run one long, non-resetting episode on bandwidth-limited edge hardware, where high-bandwidth memory and flash are scarce, flash has finite write endurance, and memory writes rather than compute can become the binding constraint.
Goal-Oriented Reasoning for RAG-based Memory in Conversational Agentic LLM Systems
arXiv:2605.12213v2 Announce Type: replace Abstract: LLM-based conversational AI agents struggle to maintain coherent behavior over long horizons due to limited context. While RAG-based approaches are increasingly adopted to overcome this limitation by storing interactions in external memory modules and performing retrieval from them, their effectiveness in answering challenging questions (e.g., multi-hop, commonsense) ultimately depends on the agent's ability to reason over the retrieved...
The Smart TV in Your LivingRoom Is a Node in the AIScraping Economy
The work at Include Security has us working with AI day in and day out (hacking it, using it, training it, etc). We’re all aware of the community-level opposition happening against datacenters, aimed at improving AI capabilities, being built recently. What you might not be aware of are the distributed efforts to train AI that could be using the devices inside your home.
PlayStation Architecture
Supporting imagery A quick introduction Sony knew that 3D hardware could get very messy to develop for. Thus, their debuting console will keep its design simple and practical… Although this may come at a cost!
Hacking your PC using your speaker without ever touching it
In my last post, I talked about reverse engineering my new Creative Sound Blaster Katana V2X's firmware. What initially started as simply wanting to write a Linux tool for communicating with my speaker ended up with me discovering vulnerabilities which allow any attacker within a ~15M range of any Katana V2X to turn it into a covert spying tool and Rubber Ducky - all without ever having to pair with or physically touch the device. CTprotocol background As I explained in my previous post, the...
The intracies of modern camera lens repair (2024)
Sigma 45mm f/2.8 Lens Repair & Analysis [05.12.24] I have a camera gear collection problem and as part of my personal 12 step plan, I restrict myself from purchasing functioning lenses. This sounds illogical, and it frankly is, but it's very hard for me to resist heavily discounted lenses.
